Outline and Purpose of the Course	Metallic crystal structure and deformation behavior are lectured on the basis of metal physics and dislocation theory. Especially, mechanical properties of dislocation and its substructure, which is changed in association with deformation, are introduced, and the effect of grain boundary and free surface on dislocation motion is explained.
Course Goals	The objective of this lecture is to deepen a further understanding of crystal growth methods, the dislocation theory and industrial problems.
