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 ... -
Environmentally assisted degradation of spinodal copper alloy C72900
Johnsen, Roy; Lange, Torstein; Stenerud, Gaute; Olsen, Jim Stian (Journal article; Peer reviewed, 2018)In this work, a spinodal Copper alloy – C72900, was tested to investigate the resistance against environmentally assisted degradation. The material was tested according to ISO 15156-3 Level V in sour H2S solution and to ... -
Hydrogen stress cracking and crack initiation in precipitation hardened Ni-alloys
Stenerud, Gaute; Johnsen, Roy; Olsen, Jim Stian (Journal article; Peer reviewed, 2018)The two different precipitation hardened nickel alloys, Alloy 718 and Alloy 725, were tested in its as received condition. Their susceptibility to hydrogen stress cracking was examined by the use of stepwise increasing ... -
