Conclusions
-
1.
In a study into the effect of sintering temperature and duration on the density, microhardness, and martensite lattice constant of a powder metallurgical maraging steel and also on the character of formation of its micro structure, the following mechanical properties were attained after sintering and aging: σB=101 kg/mm2, σ0.2=98 kg/mm2, δ=4%, ψ=12%, aH=7.9 kg-m/cm2, and HRC=25–27.

2.
The influence exerted by plastic deformation on all the mechanical properties was established. The best combination of strength and ductility, comparable with that exhibited by the cast high-strength maraging steel, was found to be ensured by a complex treatment (sintering + aging + plastic deformation + aging).
