J. Bonneville et G. Vanderschaeve, ON THE EQUILIBRIUM-CONFIGURATIONS OF CLIMB-DISSOCIATED LOMER-COTTRELLDISLOCATIONS, Philosophical magazine letters, 78(2), 1998, pp. 87-95
Equilibrium configurations of threefold composite dislocations that in
clude either intrinsic-intrinsic or intrinsic-extrinsic stacking fault
s are calculated in the framework of isotropic elastic theory. A compa
rison between the theoretical predictions and the experimental observa
tions of Lomer-Cottrell dislocations in the intermetallic alloy Ni3Ga
suggests that some of the observed configurations are not at equilibri
um.
