本文采用X射线微束衍射技术作为局部应力应变分析方法，研究了低温下尖锐缺口尖端解理裂纹形核问题和疲劳裂纹扩展问题。在这项研究中使用的材料是两种普通碳钢，碳含量为0.03%和0.31%。并将X射线应力应变测量结果与断裂力学的最新结果进行了比较。
The X-ray microbeam diffraction technique was used as a method of local stress strain analysis in order to investigate the problem of cleavage crack nucleation from the tip of a sharp notch at low temperatures and the problem of fatigue crack propagation. The materials employed in this study are two plain carbon steels with carbon contents of 0.03 and 0.31%. The results of stress strain measurement by X-rays were discussed in comparison with the recent results of fracture mechanics.
