    • Effect of different microstructural features on the hydrogen embrittlement susceptibility of alloy 718 

      Stenerud, Gaute; Wenner, Sigurd; Olsen, Jim Stian; Johnsen, Roy (Journal article; Peer reviewed, 2018)
      Due to its high strength and acceptable corrosion resistance, Alloy 718 is a viable material for the use in subsea applications. The alloy's susceptibility to hydrogen embrittlement is however limiting its viability. In ...

    • Effect of hydrogen on dislocation nucleation in alloy 718 

      Stenerud, Gaute; Johnsen, Roy; Olsen, Jim Stian; He, Jianying; Barnoush, Afrooz (Journal article; Peer reviewed, 2017)
      In situ electrochemical nanoindentation has been used to study the effect of hydrogen on the nanomechanical response of Alloy 718. Observations show that hardness increase as a result of hydrogen charging. Also, the hydrogen ...

    • Enhanced ionic conductivity of anion exchange membranes by grafting flexible ionic strings on multiblock copolymers 

      Lai, Ao NAN; Zhuo, Yizhi; Hu, Peng Cheng; Zheng, Jing Wei; Zhou, Shu Feng; Zhang, Lei (Peer reviewed; Journal article, 2019)
      A new strategy to prepare high-conductivity anion exchange membranes (AEMs) is presented here. A series of phenolphthalein-based poly(arylene ether sulfone nitrile) multiblock AEMs has been synthesized by selectively ...

    • Hydrogen-microvoid interactions at continuum scale 

      Yu, Haiyang; Olsen, Jim Stian; He, Jianying; Zhang, Zhiliang (Journal article; Peer reviewed, 2018)
      Experimentally, it has been shown that hydrogen can either enhance the internal necking failure or induce internal shearing failure of microvoids. In this study, the numerical investigation of hydrogen-microvoid interactions ...
