SIMULATION OF THE STRUCTURE OF VACANCIES IN HIGH ANGLE GRAIN BOUNDARIES.

Abstract

This study employed a hard sphere dynamic model and a bubble raft model because they have provided qualitative insight into the structure of a variety of defects in two-dimensional crystalline and amorphous systems. The computed results form part of a wider investigation of vacancies and interstitials in various grain boundaries in which the binding energies are analyzed and related to the defect structure and form of the interatomic potential.
