Dislocation Mechanisms of Plastic Deformations
FSI-9DMDAcad. year: 2020/2021
The course broadens the basic knowledge acquired in the magister course „Dislocations and plastic deformation“. It focuses deeper on the mechanisms of material´s strengthening including mathematical description. Specific dislocation mechanisms in selected important engineering materials (steels, superalloys, aluminum alloys, TiAl intermetallics, hcp metals).
Examples of the behavior of dislocations in other materials according to the focus of individual Ph.D. students.
Learning outcomes of the course unit
Ph.D. student will obtain advanced knowledge about the nature of plastic deformation including knowledge about possible quantification of dislocation mechanisms based on known models.
Good knowledge corresponding to the content of the course „Dislocations and plastic deformation“ as presented in magister study
