“…Multiple precipitates of Cu precipitates, Ni 3 Ti precipitates, and MC carbides were observed in novel ultra-high strength stainless steel with fully martensitic microstructures via tuning the composition and heat treatment processing [ 115 ]. The Cu-rich precipitates, Mo-rich precipitates, and Ni 3 (Ti, Al) phase are detected after heat treatment in maraging steels [ 64 , 116 ].…”

Precipitation hardening stainless steels have attracted extensive interest due to their distinguished mechanical properties. However, it is necessary to further uncover the internal quantitative relationship from the traditional standpoint based on the statistical perspective. In this review, we summarize the latest research progress on the relationships among the composition, microstructure, and properties of precipitation hardened stainless steels. First, the influence of general chemical composition and its fluctuation on the microstructure and properties of PHSS are elaborated. Then, the microstructure and properties under a typical heat treatment regime are discussed, including the precipitation of B2-NiAl particles, Cu-rich clusters, Ni3Ti precipitates, and other co-existing precipitates in PHSS and the hierarchical microstructural features are presented. Next, the microstructure and properties after the selective laser melting fabricating process which act as an emerging technology compared to conventional manufacturing techniques are also enlightened. Thereafter, the development of multi-scale simulation and machine learning (ML) in material design is illustrated with typical examples and the great concerns in PHSS research are presented, with a focus on the precipitation techniques, effect of composition, and microstructure. Finally, promising directions for future precipitation hardening stainless steel development combined with multi-scale simulation and ML methods are prospected, offering extensive insight into the innovation of novel precipitation hardening stainless steels.

“…For example, Mo-enriched precipitates can precipitate in different forms, such as the Fe2Mo-type Laves phase, Fe7Mo2-type ω phase, Fe7Mo6-type μ phase, trigonal R phase, and quasicrystalline R' phase, depending on the alloy composition and processing variables [17][18][19][20]. Sha et al reported that Ti is more active than Mo in the early stage of precipitation and that the precipitation behavior of Mo is modified owing to the presence of Ti, especially when aging at low temperatures [21].…”

“…In the 1960 s, maraging steel has become a research hot spot as a submarine steel [4]. The high content of Ni was found to markedly refines the lath martensite [5], Co and Mo were applied to improve the strength during aging [6,7], and further hinders the decomposition of spiral dislocation to improve the toughness and plasticity [8,9], nano-scale intermetallic compounds (Ni 3 Mo, Ni 3 Ti, et al) precipitates on ultra-low carbon dislocation martensite take the main effect on strength [10][11][12]. Among them, grade 300 maraging steel (M300) is one kind of the most widely used high-strength steel [13].…”

Additively manufactured grade 300 maraging steel (AM300) exhibits high strength but low elongation, because the precipitation strengthening effected by aging treatment has not been fully took effect. This work aims to optimize the aging treatment process of AM300. It was aged at 420°C, 500°C and 550°C for 4 h, respectively. It was found that the aged AM300 exhibited the best combination of strength and ductility (ultimate tensile strength (UTS) was 1740 MPa, total elongation (TE) was 10.2%, hardness was 520.4 HV) at 420°C. As compared to the non-aged AM300 (UTS = 1060 MPa, TE = 4.2%, hardness = 349.2 HV), the UTS, TE and hardness were increased by 64.1%, 142% and 49%, respectively.
