Point and Extended Defect Properties in H.C.P. Metals Revealed by Atomic-Scale Calculations

  • D.J. Bacon (a1)

Abstract

Recent modelling of defects in the h.c.p, metals is discussed, including the properties of vacancies and self-interstitials, and the structure of twin-boundary dislocations. Most simulations have used pair potentials, and their strengths and weaknesses are described. It is shown that an understanding of the atomic structure of h.c.p, defects is at last emerging.
