“…Moreover, the positive effects of Nb and V on preventing HE and corrosion have been reported by many researchers. [19][20][21] The Mn-added alloy was fabricated using vacuum induction melting and then hot forged at 1473 K into an 8-mm-thick plate. The alloy was homogenized at 1423 K for 2 h and then water quenched.…”

A novel metastable austenitic stainless steel denoted as 13Cr12Mn is obtained by adding 12 wt% Mn to 13Cr–5Ni–2Mo super‐martensitic stainless steel. The designed 13Cr12Mn exhibits a yield strength of 899 MPa, a tensile strength of 1068 MPa, and an elongation of 21.2%. The in situ hydrogen‐charging incremental step loading technique experiments are conducted to evaluate hydrogen embrittlement. The hydrogen‐induced cracking threshold stress of 13Cr12Mn is determined to be 961 MPa, which exceeds that of tempered S13Cr with a similar yield strength by 400 MPa. In addition, 13Cr12Mn also shows good resistance to general corrosion and pitting corrosion in alkaline solutions.

“…Microalloying is a method of adding microalloying elements such as Ti [10,11], Nb [12,13], V [14], and rare earth elements [15][16][17][18][19] to steels to enhance the mechanical properties of the steels. Among these options, the addition of Ti to steel leads to the formation of fine and dispersed TiC particles.…”

Owing to the non-uniform distribution of chemical composition and temperature during the heat treatment process, the residual stress and deformation of the workpiece emerge as crucial factors requiring consideration in managing the service performance and lifespan of shield machine cutter rings crafted from H13 steel. Considering H13 steel with titanium microalloying as the research object for the shield machine cutter ring, we simulate the quenching process using Deform-3D. The temperature field, phase transformation, stress evolution, and deformation amount after quenching are analyzed. The results demonstrate a strong agreement between the simulation and experimental results, offering valuable insights for optimizing the heat treatment process and enhancing the overall performance of shield machine cutter rings.

“…In addition, rare earth can purify molten steel and micro-alloying, which has a favourable effect on the microstructures and properties of steel [14,15]. Jiang et al [16] pointed out that appropriate amount of rare earth decreased the volume fraction of M-A constituents and the effective grain size, thus obtaining the excellent impact properties.…”

The effect of Ce on inclusion evolution in the Al-killed high-strength steel is investigated through experimental observations and thermodynamic calculations. The microstructures are analysed by scanning electron microscope (SEM), optical microscope (OM) and electron backscattered diffraction (EBSD) analysis. Mechanical properties tests are carried out to study the effect of Ce on the tensile and impact properties. The results show that after Ce treatment, the typical inclusions are modified from Al 2 O 3 inclusions and Al 2 O 3 +MnS complex inclusions to Ce-O-S inclusions, and the inclusions are refined. The area fraction, size and length/width ratio of martensite-austenite (M-A) constituents decrease with the addition of Ce. In the Ce-containing steel, the grains are finer, and the proportion of high angle grain boundaries and low-Σ coincidence site lattice boundaries is higher. Ce can improve the plasticity and impact toughness of the steel while maintaining high strength.
