“…On the other hand, Narendra et al 13 carry out aging heat treatments from 510ºC (H950) to 570ºC with intervals of 20ºC and several time conditions, it was report that specimen aging heat treated at 510ºC during 2h had maximum hardness but the values were not informed in that paper. A recent review paper reports hardness value of 49 HRC for the H950 condition 4 . The microstructure analysis of polished specimens, solution heat treated, H950 and H1000 revealed the presence of disperse titanium nitride particles in the metallic matrix.…”

“…The precipitation hardening stainless steels have been widely used in aerospace application due to its combination of strength, toughness and corrosion resistance [4][5] . In this material, the main form of corrosion is the localized corrosion (pit and crevice), where cavities formed act as stress concentrator, which can lead the material to a catastrophic failure 5 .…”

“…Jan Kazior et al [ 147 ] have examined the properties of PH17-4 steel fabricated by the powder metallurgy method, and they found that adding temperature is a very sensitive parameter to obtain high strength with satisfactory ductility. Additive manufacturing (AM) approaches as disruptive technology [ 8 , 32 , 150 , 151 , 152 , 153 , 154 ], due to their near-net-shape feature, cost-effective, and customized flexible design for complicated parts, are widely introduced to prepare PHSS gradually across multi-industries. The processing methods of AM for PHSS are still in their infancy.…”

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.

“…Maraging steels are highly interesting due to their ultra-high strength [1][2][3][4][5][6][7], crucial in contemporary frontier technology fields such as aerospace, high-speed trains, deep-sea technology, advanced nuclear energy, and clean energy [8][9][10][11][12]. For example, Wuriti et al [13] investigated the M250 maraging steel pressure vessels for aerospace applications; Dehgahi et al [14] explored high strain-rate loadings performance of maraging steel parts in industries such as high-speed train; Jha et al [15] researched the failure analysis of M250 maraging steel in solid propulsion system.…”

This paper mainly used database technology, machine learning, thermodynamic calculation, experimental verification, etc., on integrated computational materials engineering. The interaction between different alloying elements and the strengthening effect of precipitated phases were investigated mainly for martensitic ageing steels. Modelling and parameter optimization were performed by machine learning, and the highest prediction accuracy was 98.58%. We investigated the influence of composition fluctuation on performance and correlation tests to analyze the influence of elements from multiple perspectives. Furthermore, we screened out the three-component composition process parameters with composition and performance with high contrast. Thermodynamic calculations studied the effect of alloying element content on the nano-precipitation phase, Laves phase, and austenite in the material. The heat treatment process parameters of the new steel grade were also developed based on the phase diagram. A new type of martensitic ageing steel was prepared by selected vacuum arc melting. The sample with the highest overall mechanical properties had a yield strength of 1887 MPa, a tensile strength of 1907 MPa, and a hardness of 58 HRC. The sample with the highest plasticity had an elongation of 7.8%. The machine learning process for the accelerated design of new ultra-high tensile steels was found to be generalizable and reliable.
