“…1c is a side view of the specimen tested in in situ H-charging conditions at 10 − s − 1 , where a considerable number of secondary cracks are visible on the surface. This confirms the existence of H-assisted subcritical cracking, as already observed in similar materials in previous studies [2,4].…”

“…Martensitic steels are affected by hydrogen-assisted brittle fracture, that can be either intergranular or "quasi-cleavage" type [2][3][4][5][6][7]. The term "quasi-cleavage" denotes a fracture mode where fine features, like steps and tear ridges, are present in or between cleavage-like facets [5,8].…”

“…The content of reverted austenite determines the hardness and strength value, which indicates that the specimen after the aging treatment at 593 °C displays better stress corrosion cracking resistance, although the hardness is lower than the other aged samples [ 128 ]. In addition, the fracture modes of PHSS change after hydrogen charging, and hydrogen embrittlement is relieved after proper heat treatment techniques [ 129 , 130 ]. The dissolution and transformation of Ni 3 Ti precipitates and the enhanced stability of reverted austenite mainly diminish the hydrogen susceptibility after the over-aging heat treatment at 593 °C [ 130 ].…”

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.

“…Reversed austenite as an important tempered microstructure in iron and steel has been studied by researchers; the effects of alloying elements on the formation of reversed austenite have received considerable scholarly attention. Ni is the key element that promotes α-γ phase transition, while Ni gathers and provides the conditions for the reversed austenite nucleation [ 1 , 2 , 3 , 4 , 5 , 6 ]. In addition, N, Si, and other elements impact the phase transition process [ 7 , 8 , 9 , 10 , 11 ].…”

We investigated the effect of Cu on the formation of reversed austenite in super martensitic stainless steel by using X-ray diffraction (XRD), a transmission electron microscope (TEM) and an energy-dispersive spectrometer (EDS). Our results showed that the microstructure of the steels comprised tempered martensite and diffused reversed austenite after the steels were quenched at 1050 °C and tempered at 550–750 °C. The volume fraction of reversed austenite in the steel with 3 wt.% of Cu (3Cu) was more than that with 1.5 wt.% of Cu (1.5Cu). The transmission electron microscope results revealed that the reversed austenite in 1.5Cu steel mainly had the shape of a thin strip, while that in 3Cu steel had a block shape. The nucleation points and degree of Ni enrichment of reversed austenite in 3Cu steel were higher than those in 1.5Cu steel. The reversed austenite was more likely to grow in ε-Cu enriched regions. Therefore, Cu can promote reversed austenite nucleation and growth. The mechanical properties of 3 Cu steel are obviously better than those of 1.5Cu steel when tempered at 550–650 °C.
