In-situ observation of martensitic transformation in an interstitial metastable high-entropy alloy during cathodic hydrogen charging
Wang, Dong; Lu, Xu; Wan, Di; Li, Zhiming; Barnoush, Afrooz (Journal article; Peer reviewed, 2019)We show for the first time that a critical amount of dissolved hydrogen can induce a phase transformation from γ-austenite to ε-martensite in an interstitial metastable high-entropy alloy. This is demonstrated by in-situ ... -
