Abstract:

The purpose of this paper is to obtain the Cottrell atmosphere and its dragging stress τ d of an edge dislocation moving with the constant velocity \itshape v in concentrated solid solutions. Using the Fermi-Dirac distribution and Einstein's relation, the diffusion equation of the concentrated solutions is derived as
