Evaluation of the partial thermodynamic functions of the Ti-O system (up to
O/Ti = 1.5) from 1000 to 2000 K, using a methodology previously developed
for other M-O, M-R and M-N systems, is presented. Satisfactory pressure-com
position-temperature relationships for each phase have been obtained even i
n regions where no data are available. The results are presented as oxygen
isobars superimposed on the phase diagram. The Gibbs energy of oxygen disso
lution in solid titanium is also calculated. (C) 1999 Elsevier Science B.V.
