Atomic study of the trapped and migration patterns of point defects around screw dislocation in tungsten

Atomic study of the trapped and migration patterns of point defects around screw dislocation in tungsten

The interaction of 1/2 〈111〉 screw dislocation and point defects, including vacancy and self-interstitial atom (SIA), was investigated by molecular dynamics (MD) simulations. Molecular statics (MS) are used to analyze the factors affecting the binding energy of point defects around the dislocation....
