Abstract
Subgrain structures of 70 wt% copper — 30 wt% zinc brass were obtained by cold rolling and annealing. Effects of subgrain structure and orientation on fatigue properties were studied. It is found that the fatigue properties of the specimens with subgrains are superior to those of fully annealed specimens. The fatigue properties of specimens tested in the transverse direction (FT) are superior to those of specimens tested in the longitudinal direction (FL) for short annealing time. This result can be rationalized by the textured structre of the specimens in which both the resolved shear and normal stresses on the shear bands formed in FT specimens are smaller than those in FL specimens.
