Abstract

Crystal imperfections affect the stress-strain diagram in a number of ways, often increasing the tensile strength as the density of imperfections increase or their geometry creates partitioning of the crystal structure. Work hardening and strain hardening are also dependent upon imperfections. Hardness and yield stress for many metals and alloys are related by a simple relationship, σy = H/3, while the yield stress is often expressed by a Hall-Petch-type relationship, dependent upon the reciprocal square root of the grain size. These issues are presented in this chapter.
