摘　　要：利用电子背散射衍射(EBSD)技术和TEM分析方法研究了17CrNiMo6钢中一个形态上的packet内的板条马氏体的形态与晶体学特征。叙述了马氏体K-S关系的晶体学分析方法。结果表明:虽然真实马氏体取向与理想K-S关系有一定的分散,但是packet内6种变量符合K-S关系,6种K-S关系的变量之间有特定的结合。The morphology and crystallography analysis of lath martensite within a packet in 17CrNiMo6 steel was studied by electron backscattering diffraction （EBSD） with field emission gun. The procedures of the crystallographic analysis of the martensite phase with the Kurdjumov-Sachs （K- S） orientation relationship was explained. The results indicate that, although the observed orientation of the martensite crystals is scattered around the ideal variant K-S orientation, the martensite in this steel maintains the K-S orientation relationship. Specific combinations of two of the six variants are discovered.
