On the Role of Gamma-Alpha Transformation in the Increase of the Fracture Toughness of Maraging Steel

Abstract:

Based on the results of the static crack resistance tests, the contribution of the strain-induced γ→α-transformation into the fructure toughness of steel N18K9M5T with two-phase (α+γ)-structure has been assessed.
