Abstract
Earlier studies have shown that interlathaustenite in martensitic steels can enhance hydrogen embrittlement (HE) resistance. However, the improvements werelimited due to micro-crack nucleation and growth.Anovel microstructural design approachis investigated,based on enhancing austenite stability to reduce crack nucleation and growth. Our findings frommechanical tests, X-ray diffraction and scanning electron microscopy reveal that this strategy is successful. However, the improvements are limited due to intrinsic microstructural heterogeneityeffects.
