Atomistic Simulation of ½<111> Screw Dislocations in BCC Tungsten

Abstract:

Article Preview

Atomistic simulations are used to describe the ½<111> screw dislocation in tungsten. Two different embedded atom model (EAM) potentials and one bond-order potential (BOP) are compared. A new analytical approach for constructing asymmetrical screw dislocations is presented.
