Course content

The subject is introduced by a review of experimental techniques for characterising mechanical properties with emphasize on simple tensile testing. It is given an introduction to dislocation theory necessary for the understanding of the mechanical properties of metals based on their crystalline nature. In particular the structures of aluminium, steel and silicon are considered as these are of great importance for our national industry. Accordingly the basic mechanisms of yield phenomena and deformation hardening are treated. Relations between the microstructure and the mechanical properties are handled based on simple dislocation models. Furthermore, basic physical metallurgical theories for fracture and fatigue are examined. Finally an introduction is given to crystallographic texture (the crystallographic structure of metals) and anisotropic mechanical properties.

Learning outcome

The aim of the course is to provide an introduction to the basic mechanisms for hardening, fracture and fatigue of industrial important metals.

Learning methods and activities

Lectures and exercises. Lectures are given in English if there are students from the International master courses in Light Metal Production. If there is a re-sit examination, the examination form may be changed from written to oral.
