5 Materials Science and Engineering Metallurgy Ceramic engineering, Polymer chemistry Condensed matter physics Physical chemistry Applied Material Engineering Course Objectives 1. To give an overall knowledge of selected structural materials with an emphasis on application of the principles of materials science. 2. To study the relationships between processing and microstructure and between microstructure and properties 5
6 Properties are a link between the fundamental issues of materials science and the practical challenges of materials engineering Processing Optical properties of alumina (aluminium oxide) transparent translucent opaque single crystal polycrystalline polycrystalline highly perfect grain boundaries grain boundries + pores 6
7 From structure to properties Porous microstructure in polycrystalline Al 2 O 3 (a) leads to an opaque material (b). Nearly pore-free microstructure in polycrystalline Al 2 O 3 (c) leads to a translucent material. The families of engineering materials The basic families of metals, cermics, glasses, polymers, and elastomers can be combined in various geometries to create composites 7
8 Metals Ceramics Glasses High moduli, high ductility High moduli, lacking in ductility (brittle) Non-crystalline (amorphous) solid, hard, brittle and vulnerable to stress concentrations Polymers (plastics) Low moduli (50 times less than those of metals), easy to shape Elastomers Composite long-chain polymers Combinations of two or more materials, light, stiff, and strong, and they can be tough Room temperature density Room temperature stiffness (Young s modulus) 8
9 Tensile strength Resistance to fracture (Fracture toughness) Periodic table of the elements. Those elements that are inherently metallic in nature are shown in color. 9
10 Periodic table with ceramics compounds indicated by a combination of one or more metallic elements (in light color) with one or more nonmetallic elements (in dark color). Periodic table with the elements associated with commercial polymers in color. 10
