“…The main reason for such good mechanical properties of the maraging steels is the precipitation hardening during heat treatment, allowing to form a few types of nano-sized precipitates (Ni 3 (Mo, Ti), Fe 2 Mo) homogeneously dispersed within the material volume [5][6][7]. Due to their admirable properties, these steels have a wide range of applications, e.g., can be used for tooling components, aerospace and hydrospace industry, as well as for motor racing applications [4,[8][9][10]. Considering the good weldability, maraging steels are suitable for production not only via classical methods but also by way of modern processes, such as additive manufacturing [4,9,11,12] and powder metallurgy [13,14].…”
