A molecular Dynamics Study on Helium-vacancy Complexes in Tungsten under Strain Fields

应变场对钨中HenV复合体的分子动力学研究

Tungsten(W)is a promising candidate as the plasma-facing materials in fusion reactors,which suffers from helium(He)and stresses from the reactor,etc.The coupling effects of He and stress in W is an important issue for its application.In this paper,He bubble growth was investigated by molecular dynamics(MD)simulations in body-centered cubic(BCC)W under different strain fields.
