This article analyzes the influence of quenching in the wide temperature range on the amount of residual austenite, its stability and occurrence of deformation-induced martensite transformation, as well as the strengthening and wear resistance during abrasion of 150KhNML steel. Hardness and wear resistance of steels as a function of temperature are described by the curves with opposite trends, which is related with changes in content, composition of residual austenite and its deformation stability. The increase in relative wear resistance with quenching temperature is related to the microhardness of working surface after wear, which depends on the amount of formed nanocrystalline deformation-induced martensite. Formation of a secondary structure of steel working surface upon abrasion is determined by the cumulative action of friction and micro TWIP, as well as micro TRIP effects.

“…A turning-point of the 'σ-ε' curve corresponded to a strain of 5%, coinciding with the beginning of the twinning process and decreasing the strain hardening coefficient (θ) (discussed in detail below). In many papers [1,20,24,[49][50][51][52][53][54][55][56][57][58][59][60][61][62], the high hardenability of the Hadfield steel was highlighted when studying the mechanical properties of both poly [1,20,[55][56][57][58][59][60][61] and single crystals [1,20,24,[59][60][61][62]. At the same time, high values of the strain hardening coefficient (θ) and the linear nature of the 'σ-ε' dependence of the 110G13 Hadfield steel were associated with both sliding deformation and mechanical twinning.…”

The effect of tensile strains on the microstructure of Hadfield steel was studied by transmission electron microscopy (TEM). Stages of the obtained stress–strain curves were observed, and correlated well with the evolution of the dislocation substructure. Based on an analysis of TEM images, quantitative parameters were determined, such as the material volume fractions, in which slip and twinning occurred, as well as twinning, which developed in one, two and three systems. Some transformation mechanisms were reported that caused great hardening of Hadfield steel. In particular, a complex defect substructure formed in a self-organized manner due to the formation of cells, the dislocations retarded by their walls, as well as the deceleration of dislocations on twins and, vice versa, of twins on dislocations. These factors affected both the average and excess local density of dislocations. Additionally, they resulted in elastic stress fields, which manifested themselves in the curvature–torsion gradient of the crystal lattice. A high level of stresses caused by solid-solution strengthening prevented the relaxation of elastic ones, contributing to the strain hardening of the Hadfield steel.

“…Морфологически мартенсит деформации является более дисперсным по сравнению с мартенситом охлаждения. Пластическая деформация сталей и сплавов системы Fe-Mn со структурой аустенита различной стабильности вызывает также развитие процессов деформационного двойникования [11], которые активизируются с понижением температуры и ростом скорости деформации [12]. Авторы [13] считают, что деформационное двойникование может проходить параллельно с образованием мартенситных фаз деформации, а в случае повышенной стабильности аустенита -развиваться самостоятельно.…”

X-ray diffraction analysis, EBSD technique, and transmission electron microscopy are used to reveal the features of phase and microstructural transformations developing in plastic strain and fracture zones of the 05G20S2 metastable steel (Fe-20Mn-2Si). The dependence of the phase composition of the steel on the fatigue fracture surface on the value range of the stress intensity coefficient at the fatigue crack tip is determined.
