外文献翻译摘自: 《制造工程与技术(机加工)》(英文版)《Manufacturing Engineering and Technology—Machining》机械工业出版社2004年3月第1版页P560—564美s. 卡尔帕基安(Serope kalpakjian)s.r 施密德(Steven R.Schmid) 著原文:20.9 MACHINABILITYThe machinability of a material usually defined in terms of four factors:1、Surface finish and integrity of the machined part;2、Tool life obtained;3、Force and power requirements;4、Chip control.Thus, good machinability good surface finish and integrity, long tool life, and low force And power requirements. As for chip control, long and thin (stringy) cured chips, if not broken up, can severely interfere with the cutting operation by becoming entangled in the cutting zone.Because of the complex nature of cutting operations, it is difficult to establish relationships that quantitatively define the machinability of a material. In manufacturing plants, tool life and surface roughness aregenerally considered to be the most important factors in machinability. Although not used much any more, approximate machinability ratings are available in the example below.20.9.1 Machinability Of SteelsBecause steels are among the most important engineering materials (as noted in Chapter 5), their machinability has been studied extensively. The machinability of steels has been mainly improved by adding lead and sulfur to obtain so-called free-machining steels.Resulfurized and Rephosphorized steels. Sulfur in steels forms manganese sulfide inclusions (second-phase particles), which act as stress raisers in the primary shear zone. As a result, the chips produced break up easily and are small; this improves machinability. The size, shape, distribution, and concentration of these inclusions significantly influence machinability. Elements such as tellurium and selenium, which are both chemically similar to sulfur, act as inclusion modifiers in resulfurized steels.Phosphorus in steels has two major effects. It strengthens the ferrite, causing increased hardness. Harder steels result in better chip formation and surface finish. Note that soft steels can be difficult to machine, with built-up edge formation and poor surface finish. The second effect is that increased hardness causes the formation of short chips instead ofcontinuous stringy ones, thereby improving machinability.Leaded Steels. A high percentage of lead in steels solidifies at the tip of manganese sulfide inclusions. In non-resulfurized grades of steel, lead takes the form of dispersed fine particles. Lead is insoluble in iron, copper, and aluminum and their alloys. Because of its low shear strength, therefore, lead acts as a solid lubricant (Section 32.11) and is smeared over the tool-chip interface during cutting. This behavior has been verified by the presence of high concentrations of lead on the tool-side face of chips when machining leaded steels.When the temperature is sufficiently high-for instance, at high cutting speeds and feeds (Section 20.6)—the lead melts directly in front of the tool, acting as a liquid lubricant. In addition to this effect, lead lowers the shear stress in the primary shear zone, reducing cutting forces and power consumption. Lead can be used in every grade of steel, such as 10xx, 11xx, 12xx, 41xx, etc. Leaded steels are identified by the letter L between the second and third numerals (for example, 10L45). (Note that in stainless steels, similar use of the letter L means “low carbon,” a condition that improves their corrosion resistance.)However, because lead is a well-known toxin and a pollutant, there are serious environmental concerns about its use in steels (estimated at 4500 tons of lead consumption every year in the production of steels).Consequently, there is a continuing trend toward eliminating the use of lead in steels (lead-free steels). Bismuth and tin are now being investigated as possible substitutes for lead in steels.Calcium-Deoxidized Steels. An important development is calcium-deoxidized steels, in which oxide flakes of calcium silicates (CaSo) are formed. These flakes, in turn, reduce the strength of the secondary shear zone, decreasing tool-chip interface and wear. Temperature is correspondingly reduced. Consequently, these steels produce less crater wear, especially at high cutting speeds.Stainless Steels. Austenitic (300 series) steels are generally difficult to machine. Chatter can be s problem, necessitating machine tools with high stiffness. However, ferritic stainless steels (also 300 series) have good machinability. Martensitic (400 series) steels are abrasive, tend to form a built-up edge, and require tool materials with high hot hardness and crater-wear resistance. Precipitation-hardening stainless steels are strong and abrasive, requiring hard and abrasion-resistant tool materials.The Effects of Other Elements in Steels on Machinability. The presence of aluminum and silicon in steels is always harmful because these elements combine with oxygen to form aluminum oxide and silicates, which are hard and abrasive. These compounds increase tool wear and reduce machinability. It is essential to produce and use cleansteels.Carbon and manganese have various effects on the machinability of steels, depending on their composition. Plain low-carbon steels (less than 0.15% C) can produce poor surface finish by forming a built-up edge. Cast steels are more abrasive, although their machinability is similar to that of wrought steels. Tool and die steels are very difficult to machine and usually require annealing prior to machining. Machinability of most steels is improved by cold working, which hardens the material and reduces the tendency for built-up edge formation.Other alloying elements, such as nickel, chromium, molybdenum, and vanadium, which improve the properties of steels, generally reduce machinability. The effect of boron is negligible. Gaseous elements such as hydrogen and nitrogen can have particularly detrimental effects on the properties of steel. Oxygen has been shown to have a strong effect on the aspect ratio of the manganese sulfide inclusions; the higher the oxygen content, the lower the aspect ratio and the higher the machinability.In selecting various elements to improve machinability, we should consider the possible detrimental effects of these elements on the properties and strength of the machined part in service. At elevated temperatures, for example, lead causes embrittlement of steels(liquid-metal embrittlement, hot shortness; see Section 1.4.3), althoughat room temperature it has no effect on mechanical properties.Sulfur can severely reduce the hot workability of steels, because of the formation of iron sulfide, unless sufficient manganese is present to prevent such formation. At room temperature, the mechanical properties of resulfurized steels depend on the orientation of the deformed manganese sulfide inclusions (anisotropy). Rephosphorized steels are significantly less ductile, and are produced solely to improve machinability.20.9.2 Machinability of Various Other MetalsAluminum is generally very easy to machine, although the softer grades tend to form a built-up edge, resulting in poor surface finish. High cutting speeds, high rake angles, and high relief angles are recommended. Wrought aluminum alloys with high silicon content and cast aluminum alloys may be abrasive; they require harder tool materials. Dimensional tolerance control may be a problem in machining aluminum, since it has a high thermal coefficient of expansion and a relatively low elastic modulus.Beryllium is similar to cast irons. Because it is more abrasive and toxic, though, it requires machining in a controlled environment.Cast gray irons are generally machinable but are. Free carbides in castings reduce their machinability and cause tool chipping or fracture,necessitating tools with high toughness. Nodular and malleable irons are machinable with hard tool materials.Cobalt-based alloys are abrasive and highly work-hardening. They require sharp, abrasion-resistant tool materials and low feeds and speeds.Wrought copper can be difficult to machine because of built-up edge formation, although cast copper alloys are easy to machine. Brasses are easy to machine, especially with the addition pf lead (leadedfree-machining brass). Bronzes are more difficult to machine than brass.Magnesium is very easy to machine, with good surface finish and prolonged tool life. However care should be exercised because of its high rate of oxidation and the danger of fire (the element is pyrophoric).Molybdenum is ductile and work-hardening, so it can produce poor surface finish. Sharp tools are necessary.Nickel-based alloys are work-hardening, abrasive, and strong at high temperatures. Their machinability is similar to that of stainless steels.Tantalum is very work-hardening, ductile, and soft. It produces a poor surface finish; tool wear is high.Titanium and its alloys have poor thermal conductivity (indeed, the lowest of all metals), causing significant temperature rise and built-upedge; they can be difficult to machine.Tungsten is brittle, strong, and very abrasive, so its machinability is low, although it greatly improves at elevated temperatures.Zirconium has good machinability. It requires a coolant-type cutting fluid, however, because of the explosion and fire.20.9.3 Machinability of Various MaterialsGraphite is abrasive; it requires hard, abrasion-resistant, sharp tools.Thermoplastics generally have low thermal conductivity, low elastic modulus, and low softening temperature. Consequently, machining them requires tools with positive rake angles (to reduce cutting forces), large relief angles, small depths of cut and feed, relatively high speeds, andproper support of the workpiece. Tools should be sharp.External cooling of the cutting zone may be necessary to keep the chips from becoming “gummy” and sticking to the tools. Cooling can usually be achieved with a jet of air, vapor mist, or water-soluble oils. Residual stresses may develop during machining. To relieve these stresses, machined parts can be annealed for a period of time at temperatures ranging from C︒315), and then175to F︒160(F︒80to C︒cooled slowly and uniformly to room temperature.Thermosetting plastics are brittle and sensitive to thermal gradients during cutting. Their machinability is generally similar to that of thermoplastics.Because of the fibers present, reinforced plastics are very abrasive and are difficult to machine. Fiber tearing, pulling, and edge delamination are significant problems; they can lead to severe reduction in the load-carrying capacity of the component. Furthermore, machining of these materials requires careful removal of machining debris to avoid contact with and inhaling of the fibers.The machinability of ceramics has improved steadily with the development of nanoceramics (Section 8.2.5) and with the selection of appropriate processing parameters, such as ductile-regime cutting (Section 22.4.2).Metal-matrix and ceramic-matrix composites can be difficult to machine, depending on the properties of the individual components, i.e., reinforcing or whiskers, as well as the matrix material.20.9.4 Thermally Assisted MachiningMetals and alloys that are difficult to machine at room temperature can be machined more easily at elevated temperatures. In thermally assisted machining (hot machining), the source of heat—a torch, induction coil, high-energy beam (such as laser or electron beam), orplasma arc—is forces, (b) increased tool life, (c) use of inexpensive cutting-tool materials, (d) higher material-removal rates, and (e) reduced tendency for vibration and chatter.It may be difficult to heat and maintain a uniform temperature distribution within the workpiece. Also, the original microstructure of the workpiece may be adversely affected by elevated temperatures. Most applications of hot machining are in the turning of high-strength metals and alloys, although experiments are in progress to machine ceramics such as silicon nitride.SUMMARYMachinability is usually defined in terms of surface finish, tool life, force and power requirements, and chip control. Machinability of materials depends not only on their intrinsic properties and microstructure, but also on proper selection and control of process variables.译文:20.9 可机加工性一种材料的可机加工性通常以四种因素的方式定义:1、分的表面光洁性和表面完整性。
热成形钢英语
热成形钢英语Hot forming of steel is a crucial manufacturing process that plays a vital role in the production of a wide range of metal components and structures. This process involves the application of heat and pressure to reshape and transform steel into desired shapes and forms, making it an essential technique in various industries, including automotive, aerospace, construction, and manufacturing.The process of hot forming of steel typically involves heating the steel to a high temperature, usually above its recrystallization temperature, which can range from 900°C to 1250°C, depending on the specific steel grade. At these elevated temperatures, the steel becomes more malleable and easier to deform, allowing it to be shaped into complex geometries and intricate designs.One of the primary advantages of hot forming is its ability to produce parts with superior mechanical properties. The high-temperature deformation process can significantly improve the steel's strength, ductility, and overall performance characteristics. This is because the heat-induced recrystallization and grainrefinement processes that occur during hot forming can lead to the development of a more homogeneous and fine-grained microstructure, which enhances the material's resistance to deformation and failure.In addition to improved mechanical properties, hot forming also offers several other benefits. The process can be used to produce parts with complex shapes and geometries that would be difficult or impossible to achieve through other manufacturing methods, such as casting or machining. Hot forming also allows for the efficient utilization of material, as the high-temperature deformation can minimize material waste and reduce the need for extensive post-processing operations.The hot forming process can be carried out using a variety of techniques, including forging, rolling, and extrusion. Forging is a common method in which the steel is heated and then mechanically deformed using specialized tools or dies. Rolling, on the other hand, involves passing the heated steel through a series of rotating rolls to achieve the desired shape and thickness. Extrusion, in contrast, involves forcing the heated steel through a die to produce parts with a specific cross-sectional profile.Each of these hot forming techniques has its own unique advantages and is typically chosen based on the specific requirements of theapplication, such as the desired part geometry, production volume, and material properties.One of the key challenges in hot forming of steel is the management of heat and temperature during the process. Maintaining the appropriate temperature range is crucial, as excessive heat can lead to material degradation, while insufficient heat can result in incomplete deformation and poor part quality. To address this challenge, manufacturers often employ advanced heating and temperature control systems, as well as carefully designed tooling and process parameters.Another important aspect of hot forming is the consideration of residual stresses and distortion. The high-temperature deformation process can introduce internal stresses within the steel, which can lead to warping, cracking, or other undesirable deformations during or after the forming process. To mitigate these issues, manufacturers may employ various techniques, such as controlled cooling, stress relieving, or the use of specialized tooling designs.In recent years, the hot forming of steel has also seen advancements in the use of computer-aided design (CAD) and computer-aided engineering (CAE) tools. These technologies allow for the simulation and optimization of the hot forming process, enabling manufacturers to predict and address potential issues before the actual productionstage. This helps to improve the overall efficiency and quality of the hot forming process, reducing the need for costly trial-and-error approaches.Furthermore, the hot forming of steel has also been influenced by the growing emphasis on sustainability and environmental responsibility in the manufacturing industry. Manufacturers are increasingly exploring ways to reduce energy consumption, minimize waste, and improve the overall environmental impact of the hot forming process. This has led to the development of more energy-efficient heating systems, the use of renewable energy sources, and the implementation of recycling and waste management strategies.In conclusion, the hot forming of steel is a crucial manufacturing process that plays a vital role in the production of a wide range of metal components and structures. With its ability to improve mechanical properties, enable complex geometries, and offer efficient material utilization, hot forming continues to be an essential technique in various industries. As the manufacturing landscape evolves, the hot forming of steel is also adapting to meet the challenges of sustainability, technological advancements, and the ever-changing demands of the market.。

镁行业常用术语中英文对照
熔剂的反应机理镁合金的熔点不高,热容量较小,在空气中加热时,氧化快,在过热时,易燃烧,在熔融状态下无熔剂保护时,则可猛烈燃烧。
因此镁合金在熔炼过程中必须始终在熔剂和保护气氛下进行。
同时,在转移镁合金及浇注成型过程中,各种工具也需要进行洗涤和保护,这些都要涉及到熔剂。
其实熔剂的基本作用是在熔体表面形成—化学抑制层来防止熔体氧化,并去除熔体中的固态和气态的非金属夹杂物。
要选择比镁氧化亲和性更强的物质来做镁合金熔剂,最好是用碱金属和碱土金属的氯化盐和氟化盐。
镁合金熔剂主要由MgCl2、KCl、CaF2、BaCl2等氯盐及氟盐的混合物组成,它们按一定比例混匀,使熔剂的熔点、密度、黏度及表面性能均较好的满足使用要求。
其中MgCl2是起主要作用的成分,对镁熔体具有良好的覆盖作用及一定精炼能力。
主要表现在以下几个方面:1、MgCl2熔点为981K ,易与其他盐混合形成低熔点盐类混合物,迅速地铺展成一层连续、致密的熔剂层。
2、MgCl2能很好地湿润熔体表面的MgO,并将其包覆后转移到熔剂中去,消除了由MgO 所产生的绝热作用,使Mg在氧化中产生的热量能较快地通过熔剂层散出。
避免镁合金熔体表面温度急剧上升。
3、MgCl2有很大的吸湿性,裸露在空气中很快受潮,与空气中的氧及水气反应生成HCl、Cl2、H2等。
其反应如下:2MgCl2+O2=2MgO+2Cl2 MgCl2+H2O=MgO+2HCl反应生成的Cl2和HCl能迅速的和Mg反应生成MgCl22HCl+Mg= MgCl2+H2↑Mg+Cl2= MgCl2这样HCl、Cl2、H2等保护气氛及MgCl2薄层覆盖均能有效地阻止Mg与O和H2O的作用,防止氧化,抑制燃烧。
4、MgCl2具有化学造渣的作用,形成的产物MgCl2·5 MgO能从熔体中沉淀出来。
MgCl2 + 5 MgO= MgCl2·5 MgO往MgCl2中加入KCl、NaCl能够显著降低熔剂的熔点,密度,黏度,提高熔剂稳定性。
镁合金半固态射出成形技术介绍
半固態射出成形技術第一節 觸變成形技術(一)背景觸變成形主要發展里程如所示。
Dow Chemical早在1977年開始就嘗試 將半固態的概念應用在鎂合金上,經過十餘年的研究,於1988年製作出300噸 雛型機。
1900年Dow Chemical 與另外五家公司聯合成立Thixomat公司,負責 技術的商品化及授權,以及應用技術的研發,1991年獲得觸變成形設備及製程 的美國專利,之後陸續取得26國專利。
目前Thixomat授權生產觸變成形機的 公司僅限於日本製鋼所(JSW)及加拿大Husky兩家,JSW的機型包括75、220、450、650、及850噸,1998年夏天已推出1600噸機器;Husky剛取得授權不久,初期 預定開發90、225、500、及900噸等機種。
1997年為止全世界用於實際生產之 機器約65台,估計1998年底可達100台。
現有客戶三十餘家,分佈在日本、 美國、加拿大、瑞典、德國、新加坡、韓國、台灣等地,其中九成以上的客戶 原本是從事塑膠射出成形。
另一方面,美國能源部自1997年3月起展開一個400萬美金,為期三年的 計畫,支持Thixomat與Alcoa、Husky以及美國三大汽車廠合作研究鋁合金的 觸變成形,目標產品包括汽車用厚肉(8~10mm)結構件及薄殼(<1mm)連結件,未來 可能進一步擴及金屬基複合材料(metal-matrix composites)的成形技術。
(二)技術簡介觸變成形是由塑膠射出成形衍生應用在金屬的成形製程,米粒大小的金屬 顆粒原料在氬氣保護的料斗進入料管,經螺桿旋轉磨擦及料管外加熱器提供 熱量,溫度逐漸升高至其固相線溫度(solid us temperature)以上,形成部分 熔融狀態,此時螺桿同時計量後退將半固態黏漿推擠到蓄料區,待蓄儲存的黏漿 達到所需的量後,螺桿停止轉動,高速射出系統驅動桿往前推送黏漿進入模穴。
待工件完全凝固後射出單元後退,螺桿進行下一循環的剪切輸送計量,夾模單元 則開模頂出,同時進行清除廢料及噴離型劑等動作。

材控专业英语-3.Principles_of_plastic_forming
在处于热加工温度和恒应变率的奥氏体变形期间,得 到的应力-应变曲线如图3.1所示。
3.1.1 Dynamic structural changes
Fig 3.1 Equivalent stress/equivalent tensile strain curves obtained From torsion tests on low-alloy steels (AISI 1540) of initial grain size 110μm
3.1 Physical metallurgy of hot working
The structural changes taking place within the material result in an increasing dislocation density with strain until in austenitic steels and nickel-and copper-base alloys a critical strain (εc)is reached when the stored energy is sufficiently high to cause dynamic recrystallization. 材料内结构的变化产生应变,导致位错密度增加。在奥氏 体钢和镍基、铜基合金中,当储存能量足够高时会发生动 态再结晶,材料达到临界应变εc ,这时位错密度不再增加。 长句变短句,注意其中的意思连贯
为了在商业制作过程中应用这些原理,我们需要回答两个 主要的问题:a 变形之后再结晶需要多久才能发生?b 再结 晶和长大之后的晶粒尺寸是多y of hot working
The answers determine the structure of the material entering the next and subsequent passes and hence influence the flow stress of the material and the working forces required. Eventually they determine the structure and properties of the hot worked products. 答案决定了材料进行下一步以及随后过程的组织,并影响 了材料的流动应力和需要的作用力。最终影响了热加工产 品的结构和性能。

镁合金半固态成型用模具
镁合金半固态成型用模具英文回答:Magnesium alloy semi-solid forming molds are essential tools in the manufacturing process of semi-solid forming of magnesium alloys. These molds are designed to shape the semi-solid magnesium alloy into the desired form and dimensions. The use of such molds ensures consistent and accurate production of magnesium alloy components.In the semi-solid forming process, the magnesium alloy is heated to a specific temperature range where it becomes partially solid and partially liquid. This semi-solid state allows for better flow and filling of the mold cavity, resulting in improved part quality and reduced defects. The molds used in this process are typically made from high-strength materials such as tool steel or H13 steel to withstand the high temperature and pressure involved.One important consideration in the design of magnesiumalloy semi-solid forming molds is the thermal management. The molds need to be able to rapidly cool down the semi-solid magnesium alloy to solidify it and facilitate easy ejection from the mold cavity. This is achieved by incorporating cooling channels within the mold structure. These channels allow for the circulation of a cooling medium, such as water or oil, to remove heat from the mold surface and accelerate the solidification process.Another factor to consider in the design of these molds is the surface finish. The mold cavity needs to have a smooth and uniform surface to ensure proper flow of the semi-solid magnesium alloy and to minimize the occurrence of defects such as porosity or shrinkage. This can be achieved through various surface treatments, such as polishing or coating, to enhance the mold surface quality.Additionally, the mold design should take into account the ease of maintenance and repair. Since the semi-solid forming process involves high temperatures and pressures, the molds are subjected to wear and tear over time. Therefore, it is important to design the molds in a waythat allows for easy disassembly and replacement of worn-out components. This not only reduces downtime but also prolongs the lifespan of the molds.中文回答:镁合金半固态成型用模具是镁合金半固态成型制造过程中的关键工具。

镁薄板合金成形的可锻性和可成形性的加工技术摘要金属成型和金属成形机床的新发展,显示了镁薄片具有优秀的模铸性能,如果工艺是在高温下传导。
对镁薄片成型的相应的机械性能的估价,已经在各种各样的温度和应变率的条件下进行的单轴向拉力的测试。
镁合金az31b、az61b的拉深测试和m1在200-250温度范围之间都有很好可成形性,除温度之外,已经研究出的极限拉延比也影响模铸的速度。
产生的结果得出有可能由镁薄片合金混合物代替传统的铝和钢薄片的结论。
⒈引言为了减少燃料消耗、一般已经有的成就是减少汽车构造的重量的,增加重量轻的物资的使用,在这个条件下、镁合金具有对工商企业集团有特殊的使用价值,因为他们的密度低,只有1.74 g/cm3。
不久的将来镁合金将成为汽车零件模铸的主要地材料。
模具铸件技术允许放弃制造过程中复杂的几何结构。
然而,这个部分的机械性能经常不能满足机械性能的必要条件,(例如耐久强度和延性)。
一种有希望能替换的材料,毫无疑问是将模铸工艺带进简便化,那部分对机械性能和细粒的微观结构有利的没有气孔的制造技术。
然而、一种广泛被应用的模铸技术在镁合金的成型的工艺中受到了限制,模铸技术和适当的工艺参数的不完善而不得不应用(2,3)。
镁薄板金属部件的应用对汽车车身的构造提供一个很大的潜力。
通常、汽车的车身完全由板料冲压和表现大约25%飞行器质量组成。
所以,镁薄片替代传统的材料应用,将导致重量减轻的实质。
⒉镁薄片的塑料性质镁合金在室温下显示出可成形性的极限,这个六方晶体和孪晶体的倾向是唯一的允许有限的形变。
那不同地定向微晶在独立基础滑动平面显示出畸形,导致一个相互的滑动障碍(4、5)。

For the evaluation of mechanical properties relevant for forming of magnesium sheets, uni axial tensile tests have been carried out at various temperatures and strain rates.Deep drawing tests with magnesium alloys AZ31B, AZ61B, and M1 show very good formability in a temperature range between 200 and 2508C. Besides temperature, the influence of forming speed on limit drawing ratio has been investigated. The obtained results lead to the conclusion that it is possible to substitute conventional aluminum and steel sheets by using magnesium sheet metal wrought alloys.1. IntroductionIn order to reduce fuel consumption, general efforts have been made to decrease the weight of automobile constructions by an increased use of lightweight materials. In this framework, magnesium alloys are of special interest because of their low density of 1.74 g/cm3.Presently, magnesium alloys for the use as automobile parts are mainlyprocessed by die casting. The die casting technology allows the manufacturing of parts with complex geometry. However, the mechanical properties of these parts often do not meet the requirements concerning the mechanical properties (e.g. endurance strength and ductility). A promising alternative has to be seen in components that are manufactured by forming processes. The parts manufactured by this technology are characterized by advantageous mechanical properties and fine-grained microstructure without pores [1]. However, a widespread use of forming technologies for the processing of magnesium alloys is restricted because of insufficient knowledge about the forming technologies and suitable process parameters that have to be applied [2,3].Automotive body constructions offer a great potential for the application of magnesium sheet metal components.In general, the automotive body completely consists of sheet metal parts and represents a share of about 25% of the entire vehicle mass. Therefore, the substitution of conventional sheet materials by magnesium sheets would lead to essential weight savings in this application.2. Plastic material properties of magnesium sheetsMagnesium alloys show a limited formability at room temperature. This results from the fact that the hexagonal crystal structure and the low tendency to twinning only allow limited deformations. The differentlyorientated crystallites only show a deformation on the individual base slip plane, which leads to a mutual slip hindrance [4, 5]. A considerable improvement of the forming qualities can be achieved by applying temperature. The considerable increase in formability that occurs in the temperature range from 200 to2258C (depending on alloying composition) was investigated by Siebel [6]. The reason for this effect was found in the thermal activation of pyramid sliding planes in the hexagonal structure [7].2.1. Influence of forming temperature on flow stressA detailed evaluation of the deformation properties of magnesium sheets requires the determination of the material’s characteristic values like anisotropy or flow curves [8, 9].Because systematic investigations in this area are not available, extensive investigations concerning the influence of temperature and strain rate on plastic properties of various magnesium alloys were performed atInstitute for Metal Forming and Metal Forming Machine Tools (IFUM). Fig. 1 displays flow curves of magnesium sheet material AZ31B at different temperatures, determined in the uniaxial tensile test according to EN 10002, part 5.It is obvious that the stresses and possible strains largely depend on the forming temperature. The decrease of flow stresses in the temperature range above 2008C attributes to temperature-dependent relaxation.3. Deep drawing of magnesium alloysIn order to investigate the formability of magnesium sheets, deep drawing tests at different forming temperatures were carried out at IFUM with a cylindrical tool system.Fig. 3 shows the results of deep drawing tests at a temperature of 50C. Whereas the deep drawing of the alloy AZ31B using a low drawing ratio of b0 1:45 was possible (drawing depth: 30 mm), the alloys AZ61B and M1 showed early fracture. Using drawing ratio of b0 1:6, AZ31B showed fracture similar to AZ61B and M1. These tests confirm the low formability of magnesium alloys at low temperature.However, the investigated magnesium alloys show very good formability at higher temperature ,The maximum limit drawing ratio of b0 ; max 2:52 was detected for AZ31B at a forming temperature of 2008C. AZ61B and M1 show maximum values of approximately b0 ; max 2:20 up to 2.25. The values of the aluminum alloy AlMg4.5Mn0.4 are displayed for comparison. Due to the good formability of the aluminum alloy at room temperature, the increase in limit drawing ratio with rising temperature is low compared to the magnesium alloys.The results gained from the tensile tests showed the significant influence of strain rate on themechanical properties of magnesium alloys.[1] H.
