Abstract Scope It is important to investigate and calculate the hydrogen diffusion and hydrogen diffusivity related to microstructure features in order to access hydrogen embrittlemnet in nickel. In this work, the three dimensional finite element analyses (FEA) simulation based on the real microstructure representative volume element approach have been performed to determine the hydrogen diffusivity and hydrogen diffusion of clustered nanocrystalline and fine grained polycrystalline nickel. These simulations take in to consideration of the microstructure intercrystalline defects such as grain boundary and triple junctions on hydrogen activity and hydrogen diffusion. An analytical model has been developed based on FEA computation and the results are correlated with the experimental results. The experimental findings are agreed well with the computational calculated results of clustered polycrystalline nickel.
