Summary
The first section deals with structural properties of the ideals and real
crystals. The theoretical characterizations and fundamental experimental
methods are showed. The second part is focused particularly at the plastic
deformation of pure metals and alloys. The hardening and softening mechanisms
depending on various physical parameters are studied.
