<正> 正电子湮没方法已经成为金属研究的一种手段,但是由于正电子在介质中感知范围很小,目前主要用来分析金属和合金的微观结构。为了探索该方法在生产过程中的实用性。本文用它研究和分析了Fe-22at.-％Al合金的热处理制度。
Specimens of Fe-22 at-%Al subjected to different heat treatment process have beenstudied using Doppler broadening measurements. The calculated data according to the trappingmodel was shown to be in good agreement with the measured, shape parameter. The microstruc-tural change during each stage of heating and cooling has been discussed in relation to the shapeparameter, which indicates that positron annihilation data is valuable for establishing the prac-tical heat treatment process of the alloy.
