Primary creep behavior was studied in Ti-6Al-2Sn-2Zr-2Cr-2Mo-0.16Si (Ti-6-22-22S) alloy. Creep tests were performed at 480°C under various stresses in the range of 150-500 MPa. The creep behavior was analyzed in terms of Larson-Miller time to reach 0.1% creep strain. The results were compared with those in other Ti alloys as well as in Ti-6-22-22S reported by others. It is found that the creep resistance of Ti-6-22-22S is better than Ti-6Al-4V (Ti-64) and is in general agreement with that of Ti-6Al-2Sn-4Zr-6Mo (Ti-6246).
