Abstract: The stabilization of martensite in Cu-14.5%Zn-7.1Al%(mass fraction) alloy was studied by SME measurement, optical microscope observation, X-ray diffraction and TEM. In the stabilization process, the alloy exhibited reverse shape memory effect while reordering state almost didn’t change, and the density of stacking faults decreased. It is concluded that the stabilization of martensite is the process of M18R→N18R which is a diffusion shear. The similarity of the crystal transformation between M18R→N18R and β1→Mis the origin of the reverse SME in our experiment.
