Unformatted text preview: following phenomenological equations v v 1 1 = T L T L J A A AA A v vv v v 1 1 = T L T L J A A In general the vacancies are no in equilibrium, and hence v . Using the above two equations to show that , where A A A D x D v v = A A D is the selfdiffusion coefficient of A in pure A , is the vacancy diffusion coefficient in A , and x A D v v is the local mole fraction of vacancies in pure A...
