Lecture
This lecture explores the movement of dislocations under different constraints, the impact of obstacles on dislocation motion, and the role of solute atoms in influencing dislocation behavior. It also delves into the process of recrystallization, discussing the factors affecting grain growth and the influence of second-phase particles. The instructor discusses the energy associated with grain boundaries and sub-joints, as well as the kinetics of recrystallization. Various phenomena such as joint anchoring by precipitates and the effect of particles on recrystallization speed are also covered.
