High manganese steels with different contents of carbon and additionally alloyed with silicon are investigated. Mechanical properties of the steels under tensile deformation are determined, and the changes in their phase compositions are studied. The phase compositions of steels after quenching and after quenching with subsequent deformation are investigated by the X-ray diffraction method. Magnetometric measurements are performed directly during tensile deformation. It is shown that deformation has a different effect on the phase composition of steels, namely: in steel 40G20, a small amount of strain martensite is formed as a result of deformation; in steel 25G20S3, a substantial part of austenite undergoes a martensitic transformation (γ → ε).

研究了具有不同碳含量并另外添加了硅的高锰钢。测定了钢在拉伸变形下的力学性能，并研究了它们的相组成变化。用X射线衍射法研究了淬火后和淬火后变形钢的相组成。在拉伸变形过程中直接进行磁力测量。结果表明，变形对钢的相组成有不同的影响，即：在钢40G20中，由于变形形成了少量的应变马氏体；在钢 25G20S3 中，大部分奥氏体经历马氏体转变（γ → ε）。
