Hydrogen embrittlement (HE) is an inevitable problem in strengthening aluminum alloys. In the alloys, H diffusively segregates into interfacial defects such as grain boundaries and phase interfaces, weakening the atomic bonds there and causing embrittlement. Hence there is a possibility to suppress HE by reducing the interfacial segregation of H. Recently, atomic-level calculations have revealed that a second-phase particle of tin (Sn) in aluminum alloys can trap H in its interior. Furthermore, suppression of HE has been reported experimentally in tin-doped aluminum alloys. In this study, a code for simulating H diffusion in duplex steels was applied to H diffusion in aluminum containing a Sn second-phase particle to evaluate the possibility of H penetration into the particle according to the experimental conditions. As a result, it was confirmed that some amount of H can penetrate into the particles. This contributes to the verification of the experiment by simulation.
