Abstract
Two-stage pseudoelasticity in Cu-(32~16at%)Zn-(4~16at%)Al alloys and a Cu-21at%Zn-12at%Ga alloy have been investigated by tensile testing. Main interest was the influence of alloy composition and test temperature on the two-stage pseudoelasticity behavior. It has been found that the shape of the pseudoelasticity loop changes markedly depending on these factors. By reducing e/a-value below 1.42, the stress-induced α'1 phase becomes stable. In the Cu-Zn-Ga alloy slip deformation takes place before α'1 martensite is formed from β'1.
