Abstract
Dislocation motion controlled by the kink process is treated as a Brownian motion of a linearly extended object. The stress dependence of dislocation velocity, kink density and some other quantities are calculated. It is shown that when a certain condition is satisfied, the Hirth‐Lothe theory of dislocation velocity is exact.Keywords
