“…Commercial low-alloy wear-resistant steels are mainly martensitic steel, [1,4,5] besides the dual-phase [6] or complexphase [7] steel; they are typically used to increase the surface hardness to improve the wear resistance of steel plates because of low cost and simple production, which can be achieved by increasing the C content of the steel; [1,3,8] the elongation and fracture toughness of such steel plates can also improve wear resistance, [8,9] but their means of production is relatively complicated. There are also the highly studied particle-reinforced steel plates, which introduce superhard particles (e.g., TiC, [10,11] TiB 2 , [12] VC, [13] WC, [14] ) for improving the wear resistance of the material; however, these involve greater production cost and difficulty of production.…”

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.

“…The best combination of the properties was obtained for the composite with the addition of 5 wt% MoSi 2 sintered at 1300 °C. In [ 33 ], the properties of sintered composites based on a steel matrix (AstaloyCrL) reinforced with tungsten carbide (5 vol% and 20 vol%) were examined. It was shown that the volume fraction of carbides controls both abrasive wear resistance and corrosion resistance of composites.…”

The aim of this study was to carry out the consolidation of zirconium diboride-reinforced composites using the SPS technique. The effect of the adopted method of powder mixture preparation (mixing in Turbula or milling in a planetary mill) and of the reinforcing phase content and sintering temperature on the microstructure, physical properties, strength and tribological properties of sintered composites was investigated. Experimental data showed that the maximum relative density of 94%–98% was obtained for the composites sintered at 1100 °C. Milling in a planetary mill was found to contribute to the homogeneous dispersion and reduced clustering of ZrB2 particles in the steel matrix, improving in this way the properties of sintered steel + ZrB2 composites. Morphological and microstructural changes caused by the milling process in a planetary mill increase the value of Young’s modulus and improve the hardness, strength and wear resistance of steel + ZrB2 composites. Higher content of ZrB2 in the steel matrix is also responsible for the improvement in Young’s modulus, hardness and abrasive wear resistance.

“…Due to the high hardness, high wear resistance and good fatigue performance, iron-based cermets have attracted more and more attention in the field of tool manufacturing and high wear resistance tools in recent years [1][2][3].The current research focus on how to use the reinforcement phase to improve the hardness and wear resistance of Fe-based cermets [3]. Ziejewska et al [4] found that the interface between the reinforcing phase and the matrix and the content of the reinforcing phase have an important influence on the grinding performance of the cermet. Therefore, a suitable reinforcement phase is the key to make cermets.…”

The cermet based on metallic iron with zirconia toughened alumina (ZTA) as the reinforcing phase was prepared by vacuum hot-pressed sintering. The ZTA particles were subjected to electroless nickel plating to improve the interfacial bonding ability of ZTA and Fe matrix. In this paper, after electroless nickel plating, the effects of different particle sizes and different contents of ZTA particles on the grinding properties of Fe-based ZTA (Fe-ZTA) cermets were investigated. The results show that the ZTA particles are tightly bound to the Fe matrix. An interface layer is formed between the ZTA particles and the Fe matrix and it can improve the grinding ability of the Fe-ZTA cermet. By reducing the particle size and the content of ZTA particles, the friction coefficient between Fe-based ZTA cermet and the machined surface can be increased, and the surface roughness of the machined surface will reduce. When the ZTA particle size is F14 and the iron binder content is 40%, the friction coefficient between the Fe-ZTA cermet and the steel bar is 0.4981, the surface roughness of steel bar is 40.164 μm, the grinding ratio is 685.952.
