    • CuO/Cu based superhydrophobic and self-cleaning surfaces 

      He, Zhiwei; Zhang, Zhiliang; He, Jianying (Journal article; Peer reviewed, 2016)
      CuO/Cu based superhydrophobic surfaces with ordered micro/nanostructures have been prepared via a solution-immersion process combining with photolithography and argon ion beam etching. CuO nanoneedles grow only inside ...

    • The effect of plastic deformation on hydrogen diffusion in nickel Alloy 625 

      Lu, Xu; Díaz, Andrés; Ma, Jun; Wang, Dong; He, Jianying; Zhang, Zhiliang; Johnsen, Roy (Peer reviewed; Journal article, 2022)
      Recently, several hydrogen-assisted failures have been reported on different nickel alloys used in the subsea oil and gas industries. It is thus essential to correlate hydrogen uptake and diffusion behavior with stress ...

    • Hydrogen-induced transgranular to intergranular fracture transition in bi-crystalline Nickel 

      Ding, Yu; Yu, Haiyang; Zhao, Kai; Lin, Meichao; Xiao, Senbo; Ortiz, Michael; He, Jianying; Zhang, Zhiliang (Peer reviewed; Journal article, 2021)
      It is known that hydrogen can influence the dislocation plasticity and fracture mode transition of metallic materials, however, the nanoscale interaction mechanism between hydrogen and grain boundary largely remains illusive. ...

    • A predictive model unifying hydrogen enhanced plasticity and decohesion 

      Lin, Meichao; Yu, Haiyang; Ding, Yu; Wang, Gang; Olden, Vigdis; Alvaro, Antonio; He, Jianying; Zhang, Zhiliang (Peer reviewed; Journal article, 2022)
      The detrimental effect of hydrogen on metals which manifests itself as a transition from a ductile to a brittle failure mode is, for the first time, incorporated into a unified continuum-scale predictive framework. The ...

    • A simple method enabling efficient quantitative analysis of the Portevin–Le Chatelier band characteristics 

      Xu, Jianbin; Liu, Lei; Hopperstad, Odd Sture; Holmedal, Bjørn; Manik, Tomas; Marthinsen, Knut (Peer reviewed; Journal article, 2022)
      Localized deformation bands are often observed in materials exhibiting the Portevin–Le Chatelier (PLC) effect. However, efficient quantitative analysis of PLC bands remains challenging. A novel method is thus proposed in ...

    • Substrate slip steps promote cracking and buckling of thin brittle film 

      Guo, Tao; Pang, Xiaolu; He, Jianying; Zhang, Zhiliang; qiao, lijie (Journal article; Peer reviewed, 2019)
      Cracking and buckling are the two major failure phenomena of brittle film/metal substrate structures. Herein, by depositing titanium nitride brittle films with strong and poor adhesion on stainless steel substrates, we ...
