本文介绍了锰非合金化和铬和钒合金化钢的相组成和精细结构的研究，使用X射线衍射分析，光学金相，透射电子显微镜的方法。锰钢分为两类。第一组包括碳含量为1-1.2重量%的钢。第二组由0.4- 0.5wt.%碳含量各组中的Mn浓度范围为6-18重量%。结果表明，Fe-Mn-C系钢的基体是γ-Fe基固溶体（奥氏体）或α-Fe基固溶体（α-马氏体），以及γ → α相变时淬火后形成的ε-马氏体。在所有选定的C和Mn浓度下，Cr和C合金化元素的引入不改变基体的相组成，而是扩大相图的γ-区域并降低α-和e-马氏体的体积分数。断裂构造以错动带为代表。
The paper presents investigations of the phase composition and the fine structure of manganese non-alloyed and Cr- and V-alloyed steels using methods of X-ray diffraction analysis, optical metallography, and transmission electron microscopy. Manganese steel is divided into two groups. The first group includes steels with carbon content of 1–1.2 wt.%. The second group consists of 0.4–0.5 wt.% carbon content. Mn concentration in each group ranges between 6–18 wt.%. It is shown that depending on Mn and C concentration, a matrix of Fe-Mn-C steels is either γ-Fe-based solid solution (austenite) or α-Fe-based solid solution (α-martensite) as well as e-martensite formed after quenching during γ → α transformation. With all selected C and Mn concentrations, the introduction of Cr and C alloying elements does not change the phase composition of a matrix, but rather extends γ-area of phase diagram and reduces the volume fractions of both α- and e-martensite. The faulted structure is represented by the dislocation s...
