Abstract
Using the Molecular Dynamics technique the energy E vs the misorientation θ has been calculated for the CSL [001] twist grain boundaries in Cu. Two potentials have been used ; the Morse potential and a spline potential constructed by Englert and Tompa for Cu. In each case the low and high angle grain boundary regions have been clearly distinguished by using the relation E=E0θ(A-lnθ), valid for low angle grain boundaries. To this relation a polynomial has been added, in order to describe the energy vs misorientation dependence in the range (0,450).
