2) Ceramic: compounds between metallic and nonmetallic elements – oxides, nitrides, and carbides Very insulative to electricity and heat – very low electrical and thermal conductivities Highly resistant to high temperatures and corrosive environments Very hard but very brittle
Outline
• Introduction • Atomic bonding in solids • Structures of metals and ceramics • Imperfections in solids • Diffusion • Mechanical properties • Deformation and strengthening mechanisms • Failure • Phase diagrams and phase transformations • Types and applications of materials
Additional types of material
Composites; Semiconductors; and Biomaterials
They originate from the three basics (metals, ceramics and polymers), but they have special uses and functions
What is materials science and engineering
• Materials science Concerned with the relationship between
compositΒιβλιοθήκη Baiduon, structure and properties of materials • Materials engineering
Fundamentals of Materials Science
Lecturer: Shenhua SONG (宋申华)
Assessment Structure
• Written examination (50%) • Oral presentation (20%, any topics in
Chapter 7 – Mechanical Properties, 4 students as a group, 15 minutes) • Report (20%, any topics in materials science and engineering) • Assignment (10%)
To modify existing materials and develop new materials, we need to know MSE
Classification of materials
In terms of chemical makeup and atomic structure Metals; Ceramics; Polymers
1) Composites
Concerned with designing or engineering the structure to produce a predetermined set of properties
The structure of a material depends on what composition it has and how it is processed. Also, the performance of a material is a function of its properties • MSE: Composition-processing-structureproperties-performance relationship
Chapter One
Introduction
• Materials science and engineering (MSE) • Why study materials science and engineering • Classification of materials • Advanced materials
Why study materials science and engineering
All applied scientists and engineers in any engineering areas: design problems involving materials
To select a right material from many thousands according to service conditions and property requirements, we need to have the knowledge of MSE
1) Metallic: combinations of metallic elements Free electrons – good electrical and thermal conductivities Strong but deformable – extensive use in structural applications
3) Polymeric: organic compounds based on carbon, hydrogen and other nonmetallic elements – plastics and rubbers Normally low density and relatively flexible
