An apparatus has been constructed for therms1 diffusion studies of solids. This apparatus permits a virtually linear temperature gradient to be obtained. Thermal diffusion of vacancies in zinc has been studied in crystals at a mean temperature of 386ยฐC with a gradient of 5O"C/cm. A contraction of t

Quite recently it was pointed out that by rapid quenching from high temperature, it is possible t,o quench in defects that will gradually disappear with subsequent annealing at, or below, room temperature. Such observations have been carried out by anelastic measurement on solid solution(1$ 2, and h
