Document Summary
Materials science and engineering by kadri ayd nol (d-103) any version of the book (w. d. Callister, materials science and engineering an introduction) down to the 4th edition will do. Engineering properties are very much dependent on the structure of matter, although mete is not directly concerned with the structure a basic classification system for materials: Metals and alloys: metallic elements or combinations. Large number of nonlocalized electrons so good heat-electricity conductors, opaque, strong but deformable. Ceramics: metal-nonmetal compounds, heat and electricity insulators, resistant to high temperature and harsh environments, hard but brittle. Polymers: c, h and other nonmetallic based organic compounds. Composites: consists more than one type, displays a combination of best characteristics. Semiconductors: electrical properties intermediate between conductors and insulators. Biomaterials: implanted in human body, must be nontoxic and compatible with body tissues. Properties depend on structure: ex: hardness vs structure of steel.
