The major purposes of this course are to provide some fundamentals of physical metallurgy to students who have had an introductory course in materials science. And, this course will provide a theoretical base for understanding how structure is controlled; also, the way structure in turn controls the mechanical properties of metals is explained. The main topics offered in this course include: description of crystals, structure determination, plastic deformation of metal, dislocation, defects of crystals, nucleation and growth, diffusion, nanocrystal, and some applications of physical metallurgy.
