The Influence of Retained Austenite on Precipitation Hardening of Maraging Steel

The investigation of the influence of multiple solution-annealing on kinetics of structural transformation of maraging steels has shown that procedures of solution annealing are not totally reversible. Recurrent solution annealing results in the increase of the retained austenite share in maraging steel structure. In this paper the influence of retained austenite on precipitation hardening of maraging steels X2NiCoMo18-9-5 was determined. The laboratory experimental tests have shown that the growth of retained austenite share in the maraging steel structure decreases the hardness after aging.
