Abstract

The effect of reverted austenite on impact toughness, static and cyclic crack resistance of maraging steels with different strength levels has been studied. It is found that the presence of reverted austenite in the steel structure leads to an additional increase in the static crack resistance. It was is shown that in the studied maraging steels with different strength levels, the presence of reverted austenite increases the cyclic crack resistance.
