Description
Short description:
Annealing: Understand strain energy, dislocation theory, and polycrystal deformation behavior across theoretical models and cold work responses.
Long description:
This module explores the fundamental mechanisms underlying annealing-related phenomena in metals. Topics include the role of strain energy from cold work, the increase in dislocation density, and the principles of free energy in deformed structures. Learners will analyze theories of Kuhlmann-Wilsdorf and Seeger, and assess differences in behavior between single crystals and polycrystals. The module also introduces resolved shear stress and the Schmid factor, key to understanding deformation behavior at the atomic scale.
What you will learn
- Explain how cold working generates strain energy and increases dislocation density in metallic materials.
- Evaluate the stages of dislocation rearrangement and their relation to stacking fault energy and recovery processes.
