Abstract

An attempt is made to determine the diffusion coefficient of oxygen in α-Ti from oxidation studies of oxygen-unsaturated and oxygen-saturated β-Ti. Knowledge about the rates of movements of the α/β interface permits evaluation of oxygen diffusivity in α-Ti. The results conform to the relationship:D α=0.778 exp (−48,600/RT), sq cm per sec, for the temperature range of 932° to 1142°C. From microhardness measurements, the diffusion coefficient of oxygen in β-Ti can be expressed as:D β=3.30×102 exp (−58,800/RT), sq cm per soc, for the same temperature range.
