采用电子背散射衍射（EBSD）取向分析和三维成像技术对低碳马氏体钢中解理面的晶体学取向进行了研究。一种是基于三维断口图像的线轮廓，在SEM中倾斜试样后，通过EBSD直接测量解理面。另一种是对断裂面下方的EBSD方向图和三维断裂面图像的线轮廓进行跟踪分析。这两种方法均表明马氏体钢的解理断裂发生在{001}面上。
The present study determined the crystallographic orientation of the cleavage plane in a low-carbon martensitic steel by two different methods using electron backscattering diffraction (EBSD) orientation analysis and three-dimensional imaging technique. One is the direct measurement of the cleavage plane by EBSD after tilting the specimen in SEM based on the line profiles of the 3D fracture surface image. The other is the trace analysis on EBSD orientation maps just beneath the fracture surface and the line profiles of the 3D fracture surface image. The both two methods demonstrated that cleavage fracture occurred on {001} planes in martensitic steel.
