“…These tiny holes make the matrix and wear debris combining more easily. Then a thick oxide layer will be formed with the wearing process [10][11][12][13][14][15]. Therefore, the worn oxide layer of J-M42 steel with more fine carbides is thicker than that of C-M42 steel.…”

Taking Chinese-made (C-M42) and Japanese-made (J-M42) high-speed steel as research objects, the friction and wear tests were carried out and the wear mechanism was analysed. The microstructure and hardness of the two steels were observed by means of scanning electron microscope and hardness tester. Results show that J-M42 steel possesses a better wear resistance than C-M42 steel. This is related to relatively higher hardness, smaller average carbide size and higher volume fraction of carbide. There exists groove, adhesive patch and oxide layer in the worn surface. It manifests that the wear mechanisms of the two samples are adhesive wear, abrasive wear and slight oxidation wear. The overall surface roughness after wear is similar between the two steels whereas the plastic deformation layer in the vertical section of J-M42 steel is shallower than that of C-M42 steel.

“…According to the literature, it is known that DCT can promote the conversion of RA to new M, but the extent of this transformation is controversial. [40][41][42][43] Figure 4a-d shows that RA is between the boundary of MB, and the content of RA is higher in Q sample but lower in Q-T, D 5h , and D 5h -T samples. Clearly, the quantities of RA in Q-T, D 5h , and D 5h -T are less than 5% (Figure 1a), which is invisible in XRD.…”

“…However, despite the majority of experimental studies indicating the optimal effectiveness of DCT on HSS tissues, the underlying mechanism for its strong impact remains unclear and has yet to be systematically investigated. [40][41][42][43] This has resulted in poor utilization of DCT in the industry as well as considerable controversy over the increase in the performance of metal materials caused by DCT. [7,44,45] Therefore, only by an understanding of the mechanisms during DCT and the evolution of multiphase microstructures during CHT and DCT, can the enhancements of targeted properties be understood.…”

“…Fantineli et al reported that AISI M2 HSS with DCT achieved improvements in resistance to abrasive wear and toughness with a lower amount of carbon in the M together with finer and more homogeneous carbide precipitation. [ 40 ] Clearly, optimizing the heat‐treatment processes in combination with DCT can be employed to control the multiphase microstructures of HSS and achieve the expected performance.…”

It is crucial to conduct in‐depth research on the cryogenic‐treatment mechanism to promote the standardization and industrialization of cryogenic treatment in the high‐speed steel (HSS) industry. In this study, the microstructure and mechanical properties (microhardness and impact toughness) of AISI M35 HSS after deep‐cryogenic treatment (DCT) and conventional heat treatment (CHT) are investigated, and the microstructural characteristics at different stages of CHT and cryogenic treatment are studied. It is indicated in the results that DCT of the steel leads to the formation of fresh martensite from residual austenite, as well as the introduction of more dislocations due to plastic deformation. In addition, the deep‐cryogenic‐treated specimen that is tempered shows increased numbers of martensite blocks and secondary carbide precipitation. The carbides in the steel are mainly V‐rich (MC), W–Mo‐rich (M6C), and Cr‐rich (M23C6). The hardness of the deep‐cryogenic‐treated samples increases by approximately 50 HV1 because of the transformation of residual austenite and dislocation strengthening. Furthermore, specimens that are both deep‐cryogenic treated and tempered exhibit a 30% increase in impact toughness and a more uniform distribution in hardness, likely due to the more homogeneous precipitation of secondary carbides and refinement of martensite.

“…However, most studies on the DCT of the HSS are mainly focused on the residual austenite (RA) stability and secondary carbide (SCs: 0.1–5.0 μm) precipitation [ 27 , 28 ]. There are few studies on the evolution and morphology changes of lath martensite with different DCT parameters.…”

High-speed steel is widely used for cutting tools due to its convenience of preparation and cost-effectiveness. Previous research has shown that deep cryogenic treatments improve the mechanical properties of high-speed steel, due to the transformation of the residual austenite and the precipitation of carbide, while few studies have researched martensitic changes. The variations in martensite multi-level microstructures in AISI M35 high-speed steel, treated over different deep cryogenic time periods, were investigated in this study. Meanwhile, the effect of these variations on the mechanical properties of the selected steel was discussed. It was found that prolonging deep cryogenic time facilitated an increase in dislocation, low-angle grain boundary, and the coincident-site lattice boundary (especially the twin boundary) of martensite. The size of the martensite block (db) and lath (dl) decreased with deep cryogenic time. However, the effect on the microstructure was limited when the cryogenic treatment time exceeded 5 h. The increase in dislocation decreased the temperature for carbide precipitation and promoted fine carbide precipitation during tempering. The refinement of martensite multi-level microstructures and the greater precipitation of fine carbides gave the tempered specimens excellent impact toughness. The impact toughness of the tempered samples undergoing deep cryogenic treatment for more than 5 h was about 32% higher than the sample without deep cryogenic treatment.
