DIFFUSION IN TITANIUM AND TITANIUM ALLOYS

Abstract

The self-diffusion of Ti and the inter diffusion of Al, Zr, Mo, V, and O in Ti were investigated in the temperature range 600 to 1300 C. Diffusion couples were prepared by roll-bonding or press-bonding techniques. Electron microprobe methods were used to determine the penetration of the substitutionally dissolved solutes; vacuum fusion analysis was used to determine the penetration of interstitially dissolved O. The electron microprobe analysis could not be used to determine the penetration curves of Al in Ti because of the very high absorption of characteristics Al X-radiation by Ti. The self- diffusion of Ti was investigated by studying penetration of Ti(44), formed by bombarding Sc with protons. Diffusion couples were formed by dissolving Ti(44)- enriched TiO2 into the Ti.
