“…In recent studies, many researchers have analyzed the effect of Ti(C,N) particles additive on the wear-resistant steel. Prava Dalai et al [30] indicated that adding hard TiC particles into the austenitic manganese steel and secondary processing were beneficial for elastic modulus, hardness, and wear resistance. Srivastava and Das [31][32][33] demonstrated that austenite matrix with Ti(C,N) and (Ti,W)C precipitates could effectively protect the sliding surface.…”

In this study, the hot rolled medium manganese steel containing titanium was solution treated at 1,000 °C and followed by aging treatment at 500, 550, and 600 °C. The influence of aging treatment on mechanical properties and wear resistance of medium manganese steel reinforced with Ti(C,N) particles was investigated. It was found that the matrix of medium manganese steel was austenite. The austenite grain size was refined, and Ti(C,N) particles were precipitated after aging treatment. Compared to that of the as-hot rolled sample, the initial hardness of 500 °C aged sample increased by 9.5% to 312.86 HV, whose impact energy was more than doubled to 148.5 J. As the aging temperature raised to 600 °C, the initial hardness changed slightly. However, the impact energy dropped significantly to 8 J due to the aggregation of Mn at the grain boundaries. In addition, the main wear mechanisms of the samples were fatigue wear and abrasive wear. It was worth noting that 500 °C aged sample exhibited the best wear resistance under a 300 N applied load, whose wear loss was just half of the as-hot rolled sample. The relationship between wear loss and mechanical properties indicated that the wear resistance of medium manganese steel was independent of the initial hardness. The large difference in the wear resistance was predominately due to the outstanding work hardening ability of 500 °C aged sample, whose strengthening mechanisms were contributed from transformation induced plasticity (TRIP) effect, dislocation strengthening, twinning induced plasticity (TWIP) effect, and precipitation strengthening.

“…Therefore, in-situ synthesis has become an optimal method for enhancing the wear-resistant properties of steels. Among numerous ceramic particle phases, TiC represents a widely used steel reinforcing material due to its high hardness, large wear resistance, low friction coefficient, and high chemical and thermal stabilities [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24]. However, no systematic studies on the relationship between the microstructure and hardness of the insitu TiC-reinforced low alloy martensitic wear-resistant steel have been performed.…”

In this study, as-cast low alloy wear-resistant steels with Ti contents of 0.6 and 3.0 wt-% were prepared at different solidification cooling rates, and the effects of TiC formation on their microstructures, hardness values, and wear resistances were investigated. The obtained phase diagrams and experimental data revealed that the TiC phase was formed via a divorced eutectic reaction in a residual liquid phase during solidification. The larger Ti content promoted the formation of TiC particles, while the solidification cooling rate represented the main influencing factor. Moreover, the produced TiC phase increased the wear resistance of the studied steel and decreased the matrix hardness, suggesting a new method for enhancing its mechanical properties through the formation of a hard ceramic phase.
