Abstract

We investigated the fatigue crack propagation associated with a martensitic transformation from the face-centered cubic to the hexagonal close-packed phase in a Fe-15Mn-10Cr-8Ni-4Si austenitic alloy with and without hydrogen exposure (pre-charging in hydrogen gas at 10 MPa and/or testing in a hydrogen gas environment at 0.7 MPa). Unlike the case of Type 304 austenitic steel, the fatigue crack growth rate of the alloy was not affected by the hydrogen uptake at the present two hydrogen-charging conditions, although secondary cracking was increased by hydrogen.
