[2J01] Atomistic study to evaluate interactions between helium bubbles and an edge dislocation in iron

Keywords:Molecular dynamics, blanket, bubbles migration, activation energy

We investigated bubbles pipe diffusion and coalescence along an edge dislocation in iron from atomistic scale varying with the bubble distance, bubble pressure, and temperature. The threshold distances within the MD simulation time were obtained as a function of temperature and bubble pressure.
