OVERVIEW • Definition • Classification • Material Properties • Selection of Materials

Material Science - Definition • Material is a substance that serves the purpose. • Material Science is the study of the properties and applications of materials. • Materials Science involves the study of the relationships between the synthesis, processing, structure, properties, and performance of materials that enable an engineering function. » Ref : http: //www. mse. seas. upenn. edu/about-mse/mse-defined. php • It is an Interdisciplinary field involves the discovery and design of new materials, with an emphasis on solids.

Classification of Materials Ref : http: //www. mechengg. net/

Materials - Properties Physical • Appearance • Shape • Weight • Melting Point • Boiling Point etc… Chemical • • • Magnetic • Ferro Magnetism • Para Magnetism • Dia Magnetism • Permeability • Curie Temperature etc… Electrical Reactivity Corrosion Resistance Composition Acidic Nature Basic Nature etc… • • Thermal Conductivity Thermal Diffusitivity Thermal Resistivity Expansion Coefficient etc… Hysteresis Conductivity Resistivity Dielectric Strength etc… Optical • • • Reflection Refraction Diffraction Absorptive Transparency etc…

Materials - Properties Mechanical Properties : • Strength • Hardness • Elasticity • Plasticity • Vibration Resistance • Wear • Ductility • Brittlity • Malleability • • • Impact Fatigue Creep Toughness Rigidity etc. .
