chemical diffusion
@D01716@ under the influence of a @G02669@ in chemical composition. In concentrated solid solutions, e.g. A1-xBx, or in @D01716@ couples, the motion of one @C01281@ causes a counterflow of the other constituents(s) or vacancies. In this case one can define a @D01719@ for the intermixing, which is called the chemical @D01719@ or interdiffusion @C01124@.
