Atomistic study of hydrogen distribution and diffusion around a {1 1 2}<1 1 1> edge dislocation in alpha iron

Despite extensive investigations, the distribution of hydrogen around a stress singularity field is still not well understood. In this study, we conducted molecular statics (MS) analyses of the hydrogen-trap energy around a {1 1 2} edge dislocation in alpha iron. The distribution of hydrogen in crys...
