THE BAUSCHINGER EFFECT IN COPPER AND COPPER-ZINC ALLOYS

Abstract

A series of five different copper-zinc polycrystalline alloys, ranging from commercially pure copper to 65% Cu 35% Zn brass, were strained various amounts up to 5% in tension and reverse strained in compression. The Bauschinger strain is shown to be dependent on composition. An equation relating plastic strain and the Bauschinger effect is presented and experimentally verified. Preliminary data shows that the Bauschinger strain is dependent on grain size for the 65% Cu 35% Zn alloy, but is independent of grain size for the OFHC copper.
