Lecture
This lecture by the instructor covers the topic of plastic deformation, focusing on the dislocation model. The slides discuss the stages of plastic deformation, the Schmid factor, slip systems in single-crystals and polycrystals, shear stress on crystalline planes, plastic distortion, compatibility of dislocations, and the properties of the Burgers vector. The lecture also delves into dislocation loops, the Orowan equation, strain hardening, multiplying dislocations, and other hardening modes like pinning and structural hardening through precipitates. Additionally, recrystallization and the growth of crystals are explored, providing insights into the behavior of materials under stress and during recovery processes.
