This lecture covers the microscopic view of thermal activation, point defects, mobility, diffusion, grain growth, dislocations, strain energy, and the influence of atoms in solid solution. It explains the concepts of static restoration, recrystallization, and the movement of gaps in crystals. The lecture also delves into the dynamics of dislocations, the average speed of dislocations, and the factors influencing dislocation movement. Additionally, it discusses the diffusion of gaps, self-diffusion coefficients, and the impact of obstacles on dislocation movement. The influence of solute atoms on dislocation motion and the Portevin-Le Chatelier phenomenon in steel are also explored.
