| Abstract: | The samples of Cu-23% Zn-10% Al (atomic content)alloy quenched and aged have been studied by means of positron annihilation techniques.An analysis of the measured results indicates that excess vacancies and their movements,instead of the other suggested mechanisms,may be best suited for explaining thermoelastic martensite stabilization of the alloy. |

| Keywords: | positron annihilation Cu-based alloy vacancy martensite transformation |
