Description
This lecture covers the description and properties of dislocations, focusing on partial dislocations, stacking fault energy, and hardening mechanisms. It explains the sliding of dislocations in single crystals, the manifestation of plastic deformation, and the role of slip systems. The lecture also delves into crystallographic planes and directions, the critical conditions for plasticity in single crystals, and the energy considerations related to dislocations. Additionally, it discusses the stress fields induced by dislocations, the work of external forces, and the energy of dislocations in different materials.
