Structure of Materials. Instructor: Dr. Anandh Subramaniam, Department of Materials Science and Engineering, IIT Kanpur. Atomic arrangement in crystalline solids, defects in crystalline solids, microstructure evolution, quantification of microstructures. Topics includes: bonding in materials; geometry of crystals: symmetry, lattices; Miller indices; crystal structures; defects in crystals; diffusion; phase diagrams; phase transformations; and effect of microstructure on properties.
