“…Studies have shown that the higher the material strength, the greater the tendency to induce HE, especially for martensitic materials. [13,16] For the S13Cr and S13Cr-T samples, the necessity of elucidating the interplay of strength and HE was further confirmed. By adopting high-temperature tempering at 873 K for 1 h, the yield strength of S13Cr decreased from 998 to 875 MPa, and then, HEI decreased from 78% to 40%.…”

“…[11,12] Studies have shown that the higher the yield strength of martensite, the smaller the threshold of the stress corrosion cracking condition value (K 1SCC ) and the higher the susceptibility to SCC. [13] Thus, the high-strength martensitic matrix of 13Cr MSS will limit the critical conditions for service in the presence of hydrogen. Many studies have made adjustments to the chemical composition and heat treatment process to address the HE problem of 13Cr, including regulating the morphology, content, and stability of reversed and retained austenite [14] or introducing nano-precipitated phases.…”

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.

“…The combination of these elements, Cr and Cu, has been widely studied for their relevant role, jointly and separately, in the corrosion behavior of steels [45,46]. Numerous specific studies have demonstrated the relationship between yield strength and corrosion resistance [47,48]. Therefore, it is not surprising that both Cu and Cr and the action of the combination of both in steel can lead to an improvement in the yield strength of steels.…”

In complex networks, important nodes have a significant impact, both functional and structural. From the perspective of data flow pattern detection, the evaluation of the importance of a node in a network, taking into account the role it plays as a transition element in random paths between two other nodes, has important applications in many areas. Advances in complex networks and improved data generation are very important for the growth of computational materials science. The search for patterns of behavior of the elements that make up steels through complex networks can be very useful in understanding their mechanical properties. This work aims to study the influence of the connections between the elements of steel and the impact of these connections on their mechanical properties, more specifically on the yield strength. The patterns found in the results show the significance of the proposed approach for the development of new steel compositions.

“…The strength of PH13-8Mo is enhanced by precipitation strengthening of the β-NiAl precipitates with a B2 superlattice structure [7,8]. However, with increasing strength, a new problem, namely stress corrosion cracking (SCC), occurs and the SCC susceptibility increases with increasing strength [9][10][11]. Therefore, it is of great practical significance to study the SCC of ultra-high strength stainless steel.…”

Different microstructures were obtained under various thermal conditions by adjusting the heat treatment parameters of the Cr-Co-Ni-Mo series of ultra-high strength stainless steel. The effect of organizational evolution on the stress corrosion cracking (SCC) of the Cr-Co-Ni-Mo series of ultra-high strength stainless steel was investigated using potentiodynamic polarization curves, electrochemical impedance spectroscopy (EIS), transmission electron microscopy (TEM), scanning electron microscopy (SEM) and other test methods in combination with slow strain rate tensile tests (SSRTs). The results show that the Mo- and Cr-rich clusters and precipitation of the Laves phase reduce the corrosion resistance, while increasing the austenite content can improve the corrosion resistance. The Cr-Co-Ni-Mo series of ultra-high strength stainless steel has a high SCC resistance after quenching at 1080 °C and undergoing deep cooling (DC) treatment at −73 °C. With increasing holding time, the strength of the underaged and peak-aged specimens increases, but the passivation and SCC resistance decreases. At the overaged temperature, the specimen has good SCC resistance after a short holding time, which is attributed to its higher austenite content and lower dislocation density. As a stable hydrogen trap in steel, austenite effectively improves the SCC resistance of steel. However, under the coupled action of hydrogen and stress, martensitic transformation occurs due to the decrease in the lamination energy of austenite, and the weak martensitic interface becomes the preferred location for crack initiation and propagation.
