Multiple Structures of (110) CSL Twist Boundaries in fcc Metals

Authors: A. GHAFOOR, B. A. S. FARIDI, S. A. AHMAD

Abstract: The geometry of different possible structures of (110) fcc twist boundaries is explored. Computer simulation of all possible low energy structures have been carried out for \Sigma=3 and \Sigma=9 twist boundaries using many-body potentials representing copper, silver and gold. Low symmetry structures are found to have lower energies than the high symmetry CSL structures.
