利用透射电镜衬度像变化判定位错环类型及注氢纯铁中形成的位错环分析

The type identification of dislocation loops by TEM and the loop formation in pure Fe implanted with H～+

本文分两部分,第一部分研究了利用透射电镜衬度像变化判定材料中位错环类型的方法,即采用所谓inside-outside方法来判断位错环为空位型位错环或间隙型位错环.第二部分讨论了加速器注氢纯铁在673—773K时效后形成的位错环的类型.

This paper is divided into two parts： the first part is to identify the type of dislocation loops in materials by using TEM. The inside-outside method to identify V-loops or I-loops is described in detail. The second part discusses the dislocation loops in pure Fe implanted with H^＋ in a accelerator and followed by aging at 673—773 K.
