Effect of Pressure on the Diffusion of Fe in Ti and Ti + 10% Fe

View publication

Abstract

Measurements have been made of the variation of the diffusion coefficient of Fe as a function of hydrostatic pressure in Ti at 902 °C and of Fe in Ti + 10% Fe at 808 °C. Hydrostatic pressures up to 4000 atm were used. For Ti + 10% Fe the diffusion coefficient decreases with pressure and corresponds to a value of 0.6 for the ratio of the activation volume to the atomic volume. For Ti the diffusion coefficient increases nonlinearly with pressure. These results are discussed in terms of diffusion due to vacancies, interstitials, and sub‐grain boundary networks.
