Abstract
A new high strength metastable beta titanium alloy(Ti-B20) was designed according as the principle of 'near critical molybdenum equivalent and multicomponent strengthening'. The effect of solution treatment on aging response of the new alloy including room temperature tensile properties and microstructures were investigated. It is found that the tensile strength increases with the increase of solution temperatures on the same aging conditions and water quenching from solution temperatures can produce higher age hardening effect compared with air cooling. The results reveal that the specific aging response of the new alloy is from the low stability of metastable beta phase together with the effect of excess vacancy on precipitation.
