The effect of cold rolling on the structure and properties of austenitic chromium-nickel steel 12Kh18N10T is studied. X-ray diffraction analysis is performed and the microhardness of the steel is measured after rolling to different strains. The changes in the coherent scattering regions and the distortions of the crystal lattice of the steel are considered. It is shown that plastic deformation results in a mechanically induced transformation of the austenite (γ) into martensite (α′). The martensite inherits the defects formed in the process of straining of the initial phase (austenite). The data of the x-ray diffraction analysis agree with the measured microhardness of the deformed steel.

研究了冷轧对奥氏体铬镍钢12Kh18N10T组织和性能的影响。进行X射线衍射分析，并在轧制到不同应变后测量钢的显微硬度。考虑了相干散射区域的变化和钢的晶格畸变。结果表明，塑性变形导致奥氏体 (γ) 机械诱导转变为马氏体 (α')。马氏体继承了初始相（奥氏体）应变过程中形成的缺陷。X射线衍射分析的数据与变形钢的测量显微硬度一致。
