In this module, you learned about the concept of crystal defect, classification of crystal defects, non-ionic and ionic crystals of point defects, concept of dislocations, types of dislocations, dislocation movement,  dislocation glide and climb, types of surface defects, gain boundary, low and high angle gain boundaries and twin boundary.
You learned about basics of deformation, classification of deformation mechanisms, features of cataclastic deformation, localized cataclastic deformation, compaction bands, shear fractures, Cataclastic bands, granular flow, : concept of cataclastic deformation, examples of cataclastic deformation and classification of cataclastic deformation, brittle failure criteria, cohesion, fiction and byerlee’s law.
You learned about the properties of intracrystalline plasticity, deravation and physical meaning of orovan equation, work hardening, recovery, dislocation energy, dislocation temperature, the concepts of dislocation glide, climb, recrystallizattion, static recrystallizattion, dynamic recrystallizattion, grain boundary mobility and stress strain curve.
You learned about the claassifcation of deformation mechanism by diffusion, dissolution-precipitation creep, the concepts of equilibrium concentration, chemical potential and pressure, flow law of DPC, effective pressure on the surface of grains, Nabarro-Herring Creep, Coble Creep and applications of diffusion creep.
