Manufacturing Engineering and Technology—MachiningSerope kalpakjian;Steven R.Schmid机械工业出版社2004年3月第1版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 are generally 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 inresulfurized 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 of continuous 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 alumin um 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 du ring cutting. This behavior has been verified by the presence of high concentra tions of lead on the tool-side face of chips when machining leaded steels.When the temperature is sufficiently high-for instance, at high cutting spee ds 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. Le aded steels are identified by the letter L between the second and third numeral s (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 se rious 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 ste els). Bismuth and tin are now being investigated as possible substitutes for lea d in steels.Calcium-Deoxidized Steels. An important development is calcium-deoxidize d steels, in which oxide flakes of calcium silicates (CaSo) are formed. These f lakes, 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 mac hine. Chatter can be s problem, necessitating machine tools with high stiffness. However, ferritic stainless steels (also 300 series) have good machinability. M artensitic (400 series) steels are abrasive, tend to form a built-up edge, and req uire tool materials with high hot hardness and crater-wear resistance. Precipitati on-hardening stainless steels are strong and abrasive, requiring hard and abrasio n-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 com bine with oxygen to form aluminum oxide and silicates, which are hard and a brasive. These compounds increase tool wear and reduce machinability. It is es sential to produce and use clean steels.Carbon and manganese have various effects on the machinability of steels, depending on their composition. Plain low-carbon steels (less than 0.15% C) c an produce poor surface finish by forming a built-up edge. Cast steels are mor e abrasive, although their machinability is similar to that of wrought steels. To ol and die steels are very difficult to machine and usually require annealing pr ior to machining. Machinability of most steels is improved by cold working, w hich hardens the material and reduces the tendency for built-up edge formation.Other alloying elements, such as nickel, chromium, molybdenum, and vana dium, which improve the properties of steels, generally reduce machinability. T he effect of boron is negligible. Gaseous elements such as hydrogen and nitrog en 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 an d 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 strengt h of the machined part in service. At elevated temperatures, for example, lead causes embrittlement of steels (liquid-metal embrittlement, hot shortness; see Se ction 1.4.3), although at room temperature it has no effect on mechanical prop erties.Sulfur can severely reduce the hot workability of steels, because of the fo rmation 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 (aniso tropy). Rephosphorized steels are significantly less ductile, and are produced so lely to improve machinability.20.9.2 Machinability of Various Other MetalsAluminum is generally very easy to machine, although the softer grades te nd to form a built-up edge, resulting in poor surface finish. High cutting speed s, high rake angles, and high relief angles are recommended. Wrought aluminu m alloys with high silicon content and cast aluminum alloys may be abrasive; they require harder tool materials. Dimensional tolerance control may be a pro blem in machining aluminum, since it has a high thermal coefficient of expans ion and a relatively low elastic modulus.Beryllium is similar to cast irons. Because it is more abrasive and toxic, t hough, 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 to ols 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 form ation, although cast copper alloys are easy to machine. Brasses are easy to ma chine, especially with the addition pf lead (leaded free-machining brass). Bronz es are more difficult to machine than brass.Magnesium is very easy to machine, with good surface finish and prolong ed tool life. However care should be exercised because of its high rate of oxi dation and the danger of fire (the element is pyrophoric).Molybdenum is ductile and work-hardening, so it can produce poor surfac e finish. Sharp tools are necessary.Nickel-based alloys are work-hardening, abrasive, and strong at high tempe ratures. Their machinability is similar to that of stainless steels.Tantalum is very work-hardening, ductile, and soft. It produces a poor surf ace 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-up edge; 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 modul us, 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, and proper support of the work piece. Tools should be sharp.External cooling of the cutting zone may be necessary to keep the chips f rom becoming “gummy”and sticking to the tools. Cooling can usually be achi eved 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 an nealed for a period of time at temperatures ranging from to ( to ), and then 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 significa nt problems; they can lead to severe reduction in the load-carrying capacity of the component. Furthermore, machining of these materials requires careful rem oval 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 processi ng parameters, such as ductile-regime cutting (Section 22.4.2).Metal-matrix and ceramic-matrix composites can be difficult to machine, d epending on the properties of the individual components, i.e., reinforcing or wh iskers, 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 machinin g (hot machining), the source of heat—a torch, induction coil, high-energy bea m (such as laser or electron beam), or plasma arc—is forces, (b) increased too l 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 machi ning are in the turning of high-strength metals and alloys, although experiment s 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 n ot only on their intrinsic properties and microstructure, but also on proper sele ction and control of process variables.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。

Module 4 Penetrant Inspection
One of the most important aspects of penetrant inspection is the preparation of the part before the penetrant is applied. The surface must be cleaned with a solvent to remove any dirt or film. Discontinuities must be free from dirt, rust, grease, or paint, to enable the penetrant to enter the surface opening.

金属的热处理外文翻译

金属的热处理外文翻译

外文资料翻译Heat Treatment of MetalThe generally accepted definition for heat treating metals and metal alloys is “heating and cooling a solid metal or alloy in a way so as to obtain specific conditions and I or properties.”Heating for the sole purpose of hot working(as in forging operations) is excludedfrom this definition.Likewise,the types of heat treatment that are sometimes used for productssuch as glass or plastics are also excluded from coverage by this definition.Transformation Curves.The basis for heat treatment is thetime-temperature-transformation curves or TTT curveswhere,in a single diagram all the three parameters are plotted.Because of the shape of thecurves,they are also sometimes called C-curves or S-curves.Material forming processesIn this section,a short description of the process examples will begiven. But assembly andjoining processes are not described here.ForgingForging can be characterized as: mass conserving, solid state of work material (metal), andmechanical primary basic process-plastic deformation. A wide variety of forging processes areused, and Fig.9.1(a) shows the most common of these: drop forging. The metal is heated to asuitable working temperature and placed in the lower die cavity. The upper die is then lowered sothat the metal is forced to fill the cavity.[1]Excess material is squeezed out between the die facesat the periphery as flash, which is removed in a later trimming process. When the term forging isused, it usually means hot forging. Cold forging has several specialized names. The material lossin forging processes is usually quite small.Normally, forged components require some subsequent machining, since the tolerances andsurfaces obtainable are not usually satisfactory for a finished product. Forging machines includedrop hammers and forging presses with mechanical or hydraulic drives. These machines involvesimple translatory motions.金属的热处理普遍认同对金属及合金热处理的定义是,以一定的方式加热或冷却固态金属或合金,以达到一定的条件和/或获得某些性能。

电火花加工英语

电火花加工英语

电火花加工英语English: Electrical discharge machining (EDM), also known as spark machining, spark eroding, burning, die sinking, wire burning, or wire erosion, is a manufacturing process in which a desired shape is obtained by using electrical discharges (sparks). Material is removed from the workpiece by a series of rapidly recurring current discharges between two electrodes, separated by a dielectric liquid and subject to an electric voltage. One of the electrodes is called the tool-electrode, or simply the "tool" or "electrode," while the other is called the workpiece-electrode, or "workpiece." The process depends upon the tool and workpiece not making actual contact.Translated content: 电火花加工(EDM),也称为火花加工、燃烧、沉头、线切割或线腐蚀,是一种制造工艺,通过使用电放电(火花)来获得所需形状。

材料通过两个电极之间的一系列快速重复的电流放电,通过介电液体的分隔并受电压作用,从工件上去除。

③ It is used extensively for the joining of plastics, in packaging with foils(箔) and for the lap welding of sheet, foil, and thin wire.
28.4 Friction Welding (FRW) 摩擦焊
④ Welding flash, can easily be removed(容易清除) by machining or grinding.
⑤ FRW machines are fully automated, and the operator skill required is minimal.
Other Friction Welding Processes
Process capabilities:
① The ultrasonic welding process is versatile and reliable. ② It can be used with a wide variety of metallic (ductile) and nonmetallic materials, including dissimilar metals. battery assembly solar energy converter
After sufficient contact is established, the rotating member is brought to a quick stop (so that the weld is not destroyed by shearing ), while the axial force is increased. Oxides and other contaminants at the interface are removed by the radially outward movement(径向排除) of the hot metal at the interface. The pressure at the interface and the resulting friction produce sufficient heat for a strong joint to form. The shape of the welded joint depends on the rotational speed and on the axial pressure applied. These factors must be controlled to obtain a uniformly strong joint.
Process Capabilities :
① FRW can be used to join a wide variety of materials, provided that one of the components has some rotational symmetry. (轴对称) ② Solid or tubular parts (实心或管状零件)can be joined by this method, with good joint strength. ( Solid steel bars up to 100mm in diameter and pipes up to 250mm in outside diameter) ③ The surface speed of the rotating member may be as high as 900m/min, the productivity is very high (one to several ten seconds a joint).
Figure 28.3 (a) Sequence of operations in the friction welding process: (1) Lefthand component is rotated at high speed. (2) Right-hand component is brought into contact under an axial force. (3) Axial force is increased; flash begins to form. (4) Left-hand component stops rotating; weld is completed. The flash can subsequently be removed by machining or grinding. (b) Shape of fusion zone in friction welding, as a function of the force applied and the rotational speed.
28.3 Ultrasonic Welding (USW) 超声波焊接
In ultrasonic welding, the faying surfaces(结合面) of the two components are subjected to a static normal force and oscillating shearing (tangential 切线的) stresses. The shearing stresses are applied by the tip of a transducer(换能器,变换器). The frequency of oscillation is generally in the range of 10kHz to 75kHz.
Cold welding can be used to join small parts made of soft, ductile metals.
Figure 28.1 Schematic illustration of the roll bonding, or cladding process
The shearing stresses cause plastic deformation at the interface of the two components, breaking up oxide films and contaminants and thus allowing good contact and producing a strong solid-state bond. The temperature generated in the weld zone is usually in the range from one-third to one-half of the melting point of the metals joined; consequently neither melting nor fusion takes place. But different for welding plastic (low melting point).
(固态焊接)(压力焊)
Processes in which joining takes place without fusion (melting) of the workpieces. Unlike in the fusion-welding processes described in chapter 27, no liquid (molten) phase is present in the joint. ? If two clean surfaces are brought into atomic contact with each other under sufficient pressure, they form bonds (结合) and produce a strong joint. Apply external heat improves the bond by diffusion (扩散). Heat may be generated by friction, electric- resistance heating or chemical reaction.

28.2 Cold Welding (CW)[冷(压)焊]
In cold welding (CW), pressure is applied to the workpieces, through either dies or rolls (冲模或滚轮). If the rolls are used , the process is called roll bonding(滚压焊). Because of the plastic deformation involved, it is necessary that at least one, but preferably both, of the mating parts (配合件,焊接件) be ductile(易延展的). Prior to welding, the interface is degreased, wire-brushed, and wiped to remove oxide smudge(擦除氧化物污染).
