摘要
用正电子湮没Doppler展宽能谱仪和寿命仪研究了一种淬火和时效后的CuZnAl形状记忆合金,对结果的分析认为:热弹马氏体稳定化的主导因素以空位运动为好。
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.
