Evolution of the microstructure of steel 110G13L under friction is studied using the method of synchrotron x-ray diffraction and subsequent profile analysis of the diffraction peaks. Friction of the high-manganese steel is accompanied by accumulation of crystal lattice defects, which finds reflection in changes in the full widths of half maximums. The experimentally determined structural defects are a result of growth of microdistortions of the austenite lattice and reduction of the sizes of coherent scattering domains. It is shown that the friction interaction produces anisotropic displacement of the diffraction maximums of the austenite, which indicates enhanced probability of formation of stacking faults and lowering of the stacking fault energy. Obvious features of mechanically induced phase transformations have not been detected.

使用同步辐射 X 射线衍射和随后的衍射峰轮廓分析方法研究了摩擦下 110G13L 钢的显微组织演变。高锰钢的摩擦伴随着晶格缺陷的积累，这反映在半峰全宽的变化中。实验确定的结构缺陷是奥氏体晶格微畸变生长和相干散射域尺寸减小的结果。结果表明，摩擦相互作用产生了奥氏体衍射最大值的各向异性位移，这表明层错形成的可能性增加，层错能量降低。尚未检测到机械诱导相变的明显特征。
