| 摘 要： | 采用ＴＥＭ拉伸方法，对２２Ｍｎ－１３Ｃｒ－５Ｎｉ－０．２Ｎ钢断裂中出现的裂纹Ｚ字形扩展进行了原位分析，结果表明：在拉伸中裂纹Ｚ字形扩展是由材料（１１１）面相对滑动和沿（１００）面开裂两种方式交替进行完成的，这种扩展方式同晶体与外力取向有关。

| Abstract: | Z form propagation of cracks in 22Mn- 13Cr-5Ni-0.2N steel has been investigated by means of in situ tensile test in TEM. The results show that the Z form propagation of a crack in the steel is formed by the alternate progress of the relative sliding of the {111}and the cleavage along {100}, and is determined by the relative orientation between outside force and crystal. |
