... (SMSS) might be considered an advance in ordinary martensitic steel grade development, achieved by lowering carbon content and increasing key alloy elements such as nickel and molybdenum. Nitrogen may be added to improve mechanical resistance through a solid solution and, in specific cases, secondary...

In this study, 500 HBW martensitic steels with different PAG structures are investigated with a novel tuning-fork test that utilizes an integrated loadcell system. The loadcell...

... and transmission electron microscopy showed the propagation of stress corrosion cracks was associated with selective corrosion of deformation-induced martensite. The probable mechanism of transgranular SCC in this system was slip dissolution. August 1993 May 1994 1 2010 NACE International 1994...

... that was very dependent on orientation and this is ascribed to the barrier-to-crack propagation presented by the austenite stringers. Behavior generally seems to be dominated by the ferrite matrix, but the possible role of ϵ-martensite, where the ferrite is not so highly embrittled, is also discussed...
