This study examined the changes in the microstructure and phase composition of Hadfield steel depending on the content of the main elements Mn and C and the alloying elements Cr and V. Phase composition and fine structure of manganese steels were studied using X-ray diffraction analysis and electron diffraction using transmission electron microscopy. Samples of steel were undoped and were alloyed with Cr and V at a content of 0.4% and 1% by weight C and 6%-18% by weight Mn. The main phase of the steels, regardless of the Mn content, remained completely austenitic, and the introduction of Cr and V led to the expansion of the γ region. The average scalar density depended on the concentration of Mn, whereas Cr and V shifted the region of the ϵ phase toward a lower concentration of Mn and increased the content of the α phase.
