用正电子寿命和多普勒线形测量方法研究了Fe-Cr-Ni奥氏体合金淬火变形后的晶体缺陷和回复行为。讨论了缺陷恢复的机理及其相互作用。根据正电子寿命的变化，讨论了空位型缺陷与杂质原子的动态相互作用过程。
The crystal defects and the recovery behaviour in quenched and deformed Fe-Cr-Ni austenite alloys were investigated by the methods of positron lifetime and Doppler line shape measurement. The mechanism of defects recovery and their interaction were discussed. The process of dynamic interaction between vacancy-type defects and the impurity atoms was also discussed according to the changes of the positron lifetimes.
