Course content

The course is normally only every second year, next time fall 2017.

The course is intended to give a phemenological and theoretical description of the evolution in microstructure and properties during thermomechanical processing of metals and alloys. Emphasis is on sub-structure evolution during plastic deformation, dynamic and static recovery reactions and recrystallisation during annealing, and the associated evolution in mechanical properties (work hardening and softening, respectively). Some fundamental theories for deformation hardening, including different stages of hardening and the relevance of dynamic recovery will be presented, followed by models for static recovery and classical models for nucleation and growth of recrystallization.

Learning outcome

After completed the course the students should have in-depth knowledge about phenomena and reactions during plastic deformation (hot and cold) and annealing of deformed metals, including relevant theories and mathematical models (dislocation based), with emphasis on the evolution in microstructure in metals and alloys, and how this is related to their mechanical response.
After completed the course the students should be able to:
Account for some fundamentals theories and relevant mathematical models which describe the evolution in microstructure and associated properties during plastic deformation, recovery and recrystallization, herein, single- and multi-parameter dislocation based models for work hardening, models for static recovery (dislocation pattering and annihilation) and classical models for nucleation and growth of recrystallization.
Account for how different microchemistries, in terms of alloying elements in solid solution, primary and secondary phase particles of different shape, size, density and spatial distribution influence the deformation, recovery and recrystallization behavior.
Discuss, analyse and perform relevant quantitative calculations with respect to microstructure and mechanical properties during plastic deformation and subsequent annealing.

Learning methods and activities

The course will be a combination of lectures, colloquia, and self studies.
