“…The stronger the work-hardening ability of the material, the faster the surface work-hardened layer is formed, so the work-hardened layer in the stable stage of impact wear formed deeper. 9,10,17 Figure 7B provides the workhardened layer thickness, initial hardness, and surface hardness of the samples after the wear test. The Hardox450 steel exhibited the highest initial hardness, but because of its limited work-hardening ability, its wear surface hardness was the lowest among the five samples, measuring only 525 HV after a 5-h wear test.…”

“…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.

“…[7,8] Vanadium (V) is particularly attractive. [9][10][11][12][13][14] Although aging at temperatures in the range of 673 to 773 K (400 to 500 °C) has been proposed for a 0.6C-17Mn-0.45 V (in wt pct), grade [13,14] precipitation is possible at higher temperatures. [10] Higher temperature aging is more desirable due to the ability to avoid harmful carbide formation and to potentially achieve shorter treatment times but the extent to which the favorable nanoscale precipitates, such as those reported in references, [13,14] form at higher temperatures is unclear.…”

Precipitation hardening is a promising approach for strengthening of Hadfield steels. The present study examines the potential to achieve this by combining vanadium addition (up to 2 wt pct) with short-time aging (15 minutes) at 1173 K (900 °C). It was found that such a treatment is sufficient to generate a dispersion of nanoscale precipitates that provided a significant increase in hardness. Small-angle neutron scattering and transmission electron microscopy measurements were performed to quantify the particle dispersion, and Orowan precipitate hardening predictions made using the parameters thus obtained show good correspondence with the observed rates of age hardening, suggesting the precipitates are resistant to shearing. The present steels containing vanadium showed a small reduction in work-hardening capacity and this is believed to be due to carbon depletion from the matrix. It is concluded that the addition of vanadium and a short aging treatment at 1173 K (900 °C) provide a promising pathway to imparting hardness increases that provide gouge resistance during the running-in period of components made from Hadfield steel. For optimum performance, additional carbon should be added to maintain the solute carbon content of the matrix, and hence the matrix work-hardening rate.

“…Introducing hard particles into the matrix to improve the wear resistance has become a research hotspot in recent years. [17][18][19][20][21][22][23][24] For metal matrix composite materials, adding various types of ceramic particles into the metal can enable the material to effectively resist the embedding of hard abrasives without increasing the hardness of the matrix, thereby protecting the metal matrix and improving the wear resistance. [17][18][19][20] For steel materials, the wear resistance can be improved by adding second-phase precipitation elements such as Ti, V, and Nb to generate various hard precipitates in the steel through an in situ autogenous reaction.…”

“…[ 17–20 ] For steel materials, the wear resistance can be improved by adding second‐phase precipitation elements such as Ti, V, and Nb to generate various hard precipitates in the steel through an in situ autogenous reaction. [ 21–24 ] Because TiC has the advantages of high hardness, low density, low cost, and suitability for large‐scale production and smelting, Ti has become a popular choice as a second‐phase alloying element in steel. For wear‐resistant steel with a medium‐ or high‐titanium content, the eutectic reaction L → γ + TiC will occur during the solidification process to precipitate a large amount of eutectic TiC, which generally segregates near the grain boundary after the molten steel solidifies.…”

Introducing a second phase into steel to improve the wear resistance has become an effective approach for the design of wear‐resistant materials in recent years. However, efficient control of the precipitation behavior, morphology, and size of the second phase requires further research. Herein, a micrometer‐submicrometer dual‐scale TiC‐precipitated bainitic steel is prepared by treating titanium‐alloyed bainitic steel with a solid‐solution and forging (SSF) process. By comparing as‐cast sample (NSSFS) and SSF‐treated sample (SSFS) of titanium‐alloyed bainitic steel (HTBS) in terms of microstructure and TiC morphology, the regulation mechanism of the SSF process on the microstructure and the distribution of TiC is verified. The solid‐solution process places the matrix in the supersaturated state of Ti in the low‐temperature deformation zone. Subsequent forging treatment eliminates the grain boundary segregation of eutectic TiC and induces the precipitation of submicrometer TiC. The wear behaviors and mechanical properties of traditional forged ball mill liner steel (BMS) and SSFS samples are compared, and the wear performance strengthening mechanism of dual‐scale TiC is studied. The strength and wear resistance of SSFS are significantly higher than those of BMS, while its elongation and impact toughness do not decrease significantly.
