本文用发散X射线Pseudo-Kossel照相法,观察了裂纹尖端附近地区,在X射线有效穿透范围内的结构变化。结果发现,裂纹尖端附近在外载大于一定值后都可观察到所谓的“无位错区”。
In this paper, with the divergent X-ray Pseudo-Kossel photogrammetry, the structure changes near the crack tip in the effective X-ray penetration range were observed. The results show that the so-called “dislocation-free zone” can be observed near the crack tip after the external load exceeds a certain value.
