摘要： A method of heat treating Ti/Al-base alloys to improve tensile ductility and reduce the likelihood of in-service embrittlement is disclosed. The method comprises: selecting a Ti/Al-base alloy that contains a mixture of .alpha. and .alpha.2 phases, heat treating the alloy so as to form a controlled amount of .alpha.2 particles, and then cooling the alloy so as to primarily promote the growth of additional .alpha.2 on the previously formed particles, rather than the nucleation of new .alpha.2 particles. This method may be used with Ti/Al-base alloys that also comprise Sn, Ga and In as alloy constituents, and is believed to be useful for a number of Ti/Al-base engineering alloys. Alloys made by this method have been observed to maintain significant tensile ductility, even after aging at elevated temperatures under load (e.g. creep conditions).
