Introduction to Material Science: Classification of engineering materials, Structure of solids- Metallic, Ionic and Covalent bonding. Properties based on atomic bonding. Crystallography: - SC, BCC, FCC, HCP structures, APF - Theoretical density: simple problems – Miller Indices: - crystal plane and direction - Modes of plastic deformation:- Slip and twinning
Crystal imperfections – - Point defects, Line defects, Surface defects, Volume defects. edge and screw dislocations – Burgers vector – interaction between dislocations.Polishing and etching, Metallographic characterisations of metallic materials. SEM, TEM- Grain size determination Wear, Roughness, Corrosion. Diffusion in solids, fick’s laws, mechanisms, applications of diffusion in mechanical engineering, simple
problems. Applications of Diffusion.
