Course Objective

The aim of this lesson is to understand plastic deformation of metals under the macroscopic scale by searching their micro scale deformation mechanisms.

Learning Outcomes of the Course Unit

1   To recognise dislocation behaviors according to cyrstal structures,
2   To recognise single cyrstal deformation behaviors,
3   To recognise deformation behavior differences between single- and polycyrstals,
4   To analysis the effects of internal factors on deformation behaviors of metals,
5   To analysis the effects of internal factors on deformation behaviors of metals.
