“…The plate-like martensite formed after quenching will also become fine, which is conducive to improving the wear resistance of high titanium steel. The improvement of wear resistance mainly comes from the blocking effect of micron TiC inclusions on the “furrow”, and the wear resistance ( ɛ ) is approximately linear to the mass fraction of TiC inclusions in steel, which is shown as follows [ 21 , 22 ]: …”

The effects of cooling rate, Ti content, and casting temperature on titanium compounds for high titanium steel were investigated. In-situ observation of high titanium steel during remelting and solidification was carried out by using a High Temperature Confocal Scanning Laser Microscope (HTCSLM), and the observed results were in good agreement with the thermodynamic and kinetic calculations. The observation and calculation results both show that the inclusions in high titanium steel first precipitate in the form of TiN, followed by TiC precipitates as temperature decreases, eventually forming TiCxN1-x type inclusions at room temperature. The initial precipitation temperature of the inclusions increases with the increase of Ti content in molten steel, whereas casting temperature has little effect on the initial precipitation temperature of inclusions. In addition, the size of TiN inclusions increases with the increase of Ti content in steel but decreases with the increase in cooling rate.

“…[ 12 ] In recent years, researchers have attempted to add a proper amount of Ti alloy element to steel, leading to the precipitation of TiC particles in steel through chemical reactions, effectively enhancing the wear resistance of steel. [ 13,14 ] The TiC particles produced by this method are finer, more thermodynamically stable, and exhibit a more uniform size distribution in the steel matrix. Consequently, the steel products often demonstrate improved service properties and wear resistance.…”

TiC particles, known for their extremely high hardness, are commonly used in metal‐matrix composite to enhance wear resistant. Precipitating TiC particles during the solidification stage of steel proves to be an effective method for improving product properties. Herein, TiC particles are determined to precipitate during the solidification process of titanium‐containing steels (Ti>0.3 wt%) through in situ observation experiment and energy spectrum analysis. To investigate the crucial factor of wettability, which significantly affects mechanical properties, the wetting experiments between TiC substrates (15 × 15 × 2 mm) and the steel specimens (Φ3 × 3 mm) with different titanium contents (0.01, 0.31, and 0.68 wt%) are simultaneously conducted employing a modified sessile drop method, combining with an electron probe microanalyzer. The results reveal that the molten steel infiltrates into the TiC substrate along its interconnected internal pores, driven by capillary force, with elements diffusion occurring and no reaction products are found in this process. Thermodynamic calculations confirm that TiC has a higher solubility in liquid steel compared to TiN, thus validating the superior wettability of TiC–steel system over the TiN–steel system. These findings provide valuable insights for studying wettability between TiC particles and high‐titanium steel, as well as for designing high‐titanium wear‐resistant steel compositions.

“…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.
