Ti-3.5Al-5Mo-4V-2Cr-1Fe-2Zr-2Sn titanium alloy is a new high strength metastable beta titanium alloy which was designed according to the principle of ‘near critical molybdenum equivalent and multicomponent strengthening’. The effect of solution treatment on aging responses of the new alloy including room temperature tensile properties and microstructures were investigated. There is a tendency that the tensile strength is increasing with the increase of solution temperatures on the same aging conditions and water quenching from solution temperatures can produce higher age hardening effect than that treated by air cooling. The results revealed that the specific aging response of the new alloy is from the high driving force of phase precipitation together with the effect of excess vacancies.
