Abstract
A Monte-Carlo method is used to simulate the re-entrant corner growth of an fcc (111) crystal surface on which emerged the outcrop of a twin lamella of type A, composed of parallel stacking faults bounded by partial dislocations. The results are compared with those of twin lamellae of type B, stacking fault and screw dislocation mechanisms. It is found than the activity of the re-entrant corner mechanism induced by the A-type lamella is smaller than that of the B-type twin lamella mechanism, and that it is larger than that of the stacking fault mechanism. However, it is less than that of the screw dislocation mechanism at low supersaturation.
