The paper investigates the influence of alloying of high manganese steel with various materials on its wear resistance. It describes the results of differential scanning calorimetry and thermo-gravimetric analysis obtained in the process of thermal investigation of high manganese steel alloyed with different materials. The processes taking place in alloyed high manganese steel during heat treatment were considered. Besides, the paper shows the results of investigation of kinetics of oxidation of high manganese steels, temperatures of the start and completion of carbide decomposition and carbon burning; the comparative analysis of these processes was carried out. The research group determined the qualitative characteristics of the steel decarburization process depending on the implemented alloying scheme of high manganese steel. Scientific justification was given to the results obtained in the research work. The technological recommendations, which make it possible to calculate the optimum hardening temperature of high manganese steels, were given. General conclusions were made in the final part of the paper.

This article is focused on the mechanical behavior and its relationship with the microstructural changes observed in two high-manganese steels presenting twinning-induced plasticity (TWIP) and transformation-induced plasticity (TRIP), namely Steel B and Steel C, respectively. Chemical compositions were similar in manganese, but carbon content of Steel B approximately doubles Steel C, which directly impacted on the stacking fault energy (SFE), microstructure and mechanical response of each alloy. Characterization of as-cast condition by optical microscope revealed a fully austenitic microstructure in Steel B and a mixed microstructure in Steel C consisting of austenite grains and thermal-induced (εt) martensite platelets. Same phases were observed after the thermo-mechanical treatment and tensile tests, corroborated by means of X-Ray Diffraction (XRD), which confirms no phase transformation in Steel B and TRIP effect in Steel C, due to the strain-induced γFCC→εHCP transformation that results in an increase in the ε-martensite volume fraction. Higher values of ultimate tensile strength, yield stress, ductility and impact toughness were obtained for Steel B. Significant microstructural changes were revealed in tensile specimens as a consequence of the operating hardening mechanisms. Scanning Electron Microscopy (SEM) observations on the tensile and impact test specimens showed differences in fracture micro-mechanisms.
