Electronic Structure Calculations of Oxygen Atom Transport Energetics in the Presence of Screw Dislocations in Tungsten
Plastic flow in body-centered cubic (bcc) alloys is governed by the thermally-activated motion of screw dislocations in close-packed planes.In bcc interstitial solid solutions, solute diffusion can occur at very fast rates owing to low migration energies and solute concentrations.Under mechanical loading, solutes may move on the same or similar tim
