It has been shown that edge dislocations in molybdenum (modeled by a Finnis-Sinclair potential), and by inference in other bcc transition metals, can support stable dislocation kink pairs. Motion of the edge dislocation by nucleation and migration of kink pairs can take place at a stress much smaller than the calculated value of 0.006{micro} required for translation of the rigid dislocation, and should be athermal for temperatures above 10K.
