Abstract

Polycrystalline 70−30 brass of varying grain size has been studied. Measurements were made of slip line lengths on the polished surface of specimens which had undergone different plastic strains. A relation between the slip line length and the grain size and plastic strain was found based on experimental data using a multiple regression technique. Qualitative agreement was found between the observed slip lengths and slip lengths calculated from a published work-hardening model. The effect of the boundary on slip behavior was observed, and both passive and active types of obstruction to slip by boundaries are suggested.
