Abstract

Studied the characteristics of the mechanical properties of maraging steels in the alloying system Fe–Ni–Mo–Ti–Al, wherein the content of Ti after different heat treatment. Determined the technological parameters of aging, providing an optimal combination of strength properties of steels and their level of impact strength. Given microstructure steels under different heat treatment conditions. Described the dependences of mechanical properties from the cross-sectional dimensions of rods. Studied the influence of titanium on the mechanical properties of steels.
