Lamination: Deformation, Ductility, and Dislocations

This lecture covers the process of lamination, focusing on cold deformation and hot rolling. It explains the concepts of ductility, plastic deformation, and dislocations in materials, as well as the effects of strain rate and temperature. The presentation delves into the characteristics of different materials, the behavior of dislocations in crystals, and the mechanisms of hardening through work hardening. The instructor discusses the relationship between plastic flow stress and dislocation density, as well as the impact of obstacles on dislocation movement. Various types of dislocations, such as edge and screw dislocations, are also explored.
