“…Maraging steels are highly alloyed steels with a low carbon content which exhibit excellent mechanical resistance, combined with good toughness and ductility [1][2][3][4][5][6]. The austenite-to-martensite transformation in maraging steels contrasts sharply with that of conventional steels, since its low carbon content results in a tough and ductile martensite [1,2,[4][5][6]. The main strengthening mechanism of maraging steels occurs during appropriate aging heat treatments, causing precipitation of intermetallic phases such as Fe2Mo, Fe7Mo6, Ni3Ti and NiAl , providing a tensile strength above 1500 MPa [1][2][3][4][5][6].…”

Cyclic heat treatment is an effective approach for enhancing the mechanical properties of 18Ni(C250) maraging steel, and the selection of cyclic heat treatment temperature is a key factor. In this study, a cyclic heat treatment process with a two-step solution treatment is employed to investigate the influence of cyclic heat treatment temperature, specifically the first solution treatment temperature (920 °C, 950 °C, and 980 °C), on the microstructure and mechanical properties of 18Ni(C250) maraging steel. The results indicate that with an increase in the cyclic heat treatment temperature, the average grain size of the 18Ni(C250) maraging steel decreases initially and then increases. When the cyclic heat treatment temperature reaches 950 °C, the grain size is at its minimum, exhibiting optimal grain uniformity. Additionally, the increase in cyclic heat treatment temperature results in a reduction in the size of martensitic lath with the same orientation inside the grains, along with an increase in the relative quantity of low-angle grain boundaries. Furthermore, the volume fraction and size of retained austenite show a monotonous increase with the rise in the temperature of the cyclic heat treatment, and the rate of increase becomes notably larger when the temperature is raised from 950 °C to 980 °C. Based on the observed microstructural changes, the variation in the mechanical properties of the 18Ni(C250) maraging steel was analyzed. Specifically, as the cyclic heat treatment temperature increases, the tensile strength of the 18Ni(C250) maraging steel initially increases and then stabilizes, while the elongation and fracture toughness exhibit a monotonic increase.
