The S-lineshape parameter measurements of positron annihilation Doppler-broadening were performed for a Cu-23.48at%Zn-8.63 at%A1 shape memory alloy. The S-parameters progressively decrease with prolonged holding at room temperature. The result showed that the state containing martensitic and parent phase has an aging effect
of which micromechanism is an annihilation of vacancies.
