Abstract
Computer simulation of the slippage of both an isolated screw dislocation with Burgers vector a0/2〈110〉, and a dislocation interacting with monovacancies in ordered AuCu3 is carried out. Interaction between atoms in the alloy is described by Morse potential functions. The Peierls potential pattern overcome by the screw dislocation as it slips and its distortion in a neighborhood of gold and copper monovacancies are calculated. The limits of applicability of elastic continuum theory are discussed for calculations of dislocation-vacancy interaction.
