To extend service life of Cr‐Mo‐V hot‐working die steel, a method of alloying with nitrogen‐substituted carbon is proposed. The mechanical properties of the test steels in the long‐time heating and holding process are measured. The effect of nitrogen‐substituted carbon on thermal stability is characterized and analyzed by means of scanning electron microscopy (SEM), transmission electron microscopy (TEM), and Thermo‐Calc. The results show that the ratio of N in V(C,N) can be increased by nitrogen‐substituted carbon at high temperature, which significantly improves its stability. As a result, it can not only refine the grain but also broaden the austenitizing temperature range and promote the complete solution of alloy elements such as Cr, Mo. In the process of long‐term heating and insulation, nitrogen‐substituted carbon can effectively reduce the precipitation of harmful carbides and the coarsening rate by raising the activation energy of tempering transformation with 20.0 kJ mol−1, and increase the precipitation of the main strengthening phase V(C,N). Nitrogen‐substituted carbon, as an effective alloying method, innovatively improves thermal stability and service life of Cr‐Mo‐V hot‐working die steel.

“…Coating technology is put forward to enhance the friction-wear performance [8,9], NiCr coating with high wear resistance [10][11][12] is a hard coating, the additions of Cr 3 C 2 and MoS 2 [13][14][15][16][17][18][19] may improve the hardness and lubrication performances. Among them, Cr 3 C 2 has the strongest anti-oxidation ability at high temperature, the fabricated coating has the advantages of strong bonding ability and uniform structure [20][21][22]; and MoS 2 is used as a solid lubricant, which effectively reduces the Coefficient Of Friction (COF) [23][24][25].…”

Cr 3 C 2 -NiCr+10%Ni/MoS 2 composite coating was fabricated on H13 hot work mould steel using a Laser Thermal Spraying (LTS). The friction-wear behaviors of obtained coating at 25, 400 and 700°C were investigated using a ball-on-disc wear tester, and the effect of MoS 2 on the lubrication in the friction-wear process was also discussed. The results show that the average coefficients of friction (COFs) of Cr 3 C 2 -NiCr+10%Ni/MoS 2 coating at 25, 400 and 700°C are 0.68, 0.55, and 0.35, respectively, and the corresponding wear rates are 25.97×10 -6 , 30.06×10 -6 , and 11.86×10 -6 mm 3 ·N -1 ·s -1 , respectively. The average COF and wear rate at 700°C are the lowest among the three kinds of operation temperatures, the MoS 2 particles and oxidation layer play a positive role of lubrication, which is the main factor of friction-wear reduction. The wear mechanism at 25°C is abrasive wear, while those at 400 and 700°C are primary abrasive wear, accompanied by oxidative wear.

The material of disc cutters is important to full-face tunnel boring machines (TBM). In recent years, disc cutters were optimized and tested by many scholars all around the world. H13(4Cr5MoSiV1) steel is widely used due to its excellent properties, especially in TBM disc cutters. In this paper, H13 steel with optimized composition was prepared and heat treatment. The high temperature compression of H13 steel was conducted at the temperatures ranging from 100 °C to 700 °C, with strain rate at 0.01 s−1. The stress-strain curves, Rockwell hardness and microstructure of H13 steel after compression were obtained and analyzed. The results showed that the compression strength and hardness decreased as the temperature increased; and the compression strength, hardness and ductility decreased rapidly between 600 °C and 700 °C, HR700 (the hardness of H13 steel at 700 °C) only reached 33.23 HRC. It is not recommended for TBM disc cutters to work in an environment over 600 °C.
