Abstract
Extensions and the activation energies necessary for the constriction of dissociated jogs are calculated in the piecewise-straight dislocation segment model. Because the energy of the stair-rod pair in the jog is quite uncertain, the results are presented in such a way that one may predict jog extensions and activation energies as a function of the stair-rod energy. The energy of a stair-rod pair is estimated from experimental results on vacancy energies. The results indicate a considerable variation in the activation energy for different materials. For silver it is almost an order of magnitude larger than for copper and gold, which materials in turn have a considerably higher activation energy than aluminium and nickel.Keywords
