On thermodynamic parameters of self-diffusion

Creators

Description

Analytical expressions for calculating Gibbs free energy, entropy, enthalpy and activation volume of self-diffusion, as well as preexponential factor, depending on temperature and pressure in crystal volume of elementary substance, were obtained. Calculation, conducted for 29 elementary cubic crystals, including Li, Na, Cs, Ni, Nb, Mo, showed satisfactory agreement of mentioned parameters with corresponding experimental values. Substantiation of some known phenomenological relations between self-diffusion parameters is given. 35 refs.; 5 tabs
