“…For a slight differences in toughness and plasticity, there are direct correlations between the strength and hardness of the material (Table 2) and the wear resistance unless the microstructure undergoes significant local structure changes under the wear conditions, such as the transformation induced plasticity effect [24] and addition of second-phase particles. [25] The wear surface morphology of the samples after 60 min is shown in Figure 7. Figure 7a1-c1 shows the 3D morphology of the wear surfaces of the Q345, DQ, and RQ samples, respectively, which exhibit different degrees of roughness under the action of abrasive impact and sliding.…”

Herein, thermomechanically controlled processing (TMCP) and direct‐quenching (DQ) process are investigated to improve the mechanical and wear properties of wear‐resistant steel, compared to the reheating–quenching (RQ) process. Scanning electron microscope, electron backscatter diffraction, transmission electron microscope, and X‐ray diffraction are employed to characterize the microstructures of the DQ and RQ specimens, and the mechanical and wear properties are investigated using the Vickers hardness, impact, tensile, and stirring wear tests for both processes. The results show that DQ steel exhibits strong plasticity, impact toughness, and wear resistance; the DQ process also retains the deformed austenite formed by rolling in the nonrecrystallization region. The compressed austenite reduces the size of the martensite lath and block structure, increases the density and proportion of the high‐angle grain boundaries, and improves the plasticity and toughness of DQ steel. Meanwhile, DQ steel also inherits the high‐density dislocations created during the rolling process, which is its primary strengthening mechanism. The deformed grains in DQ steel reduce the Schmid factor, improve resistance to wear deformation, and enhance its wear performance.

“…References [13][14][15][16] have been reported on the medium manganese (8-12 wt%) steel. In addition, the mechanical properties and wear resistance were improved by adding Ti, Cr, Mo, and V elements into the steel to obtain the solution and precipitation strengthening effects [17][18][19][20][21][22]. Thus, the alloying, heat treatment, work hardening, and wear performance of medium manganese wear-resistant steel have been systematically studied [23][24][25][26][27].…”

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.

“…Plastic deformation and fatigue failure of material surface under impact-abrasive wear conditions [1][2][3][4] have always been a major problem that needs to be addressed in the development of wear-resistant steel. Improving the hardness and strength is the main idea to improve the wear resistance of materials, and the methods include alloying modification, [5][6][7] introduction of second-phase particle, [8][9][10][11][12] surface modification, 13,14 and so on. However, the improvement of material strength and hardness often sacrifices toughness, which may lead to brittle spalling of the material surface, thereby deteriorating the wear performance.…”

This study aims to revealing the relationship among retained austenite (RA) morphology, deformation‐induced transformation (DIPT) behavior, and surface wear behavior. The hardening and fatigue behavior during wear of continuous film‐like RA (CFRA), blocky RA (BRA), discontinuous film‐like RA (DFRA), and point or flocculent RA (PRA) achieved through different tempering processes was investigated using quasi‐in situ fatigue test and impact abrasive wear test. RA morphology exhibited a significant influence on hardening and fatigue behavior during wear. CFRA exhibited the best wear properties, owing to its excellent fatigue performance and hardening capacity. The BRA displayed relative high wear performance, with adequate hardening capacity but weak fatigue performance. DFRA demonstrated comparable wear resistance to BRA because of better fatigue performance. PRA exhibited deficient wear performance because of insufficient fatigue properties and low work‐hardening ability.
