Abstract
The microstructure evolution as well its effect on the mechanical properties of Ti–15Mo alloys after solution treatment (ST), cold rolling (CR) and aging after cold rolling (CRA) were investigated. The Young’s modulus of the alloys after ST, CR and CRA are all less than 60 GPa. The Young’s modulus for the CR and CRA samples is slightly higher than that for the ST samples owing to the ω phase caused by mechanical twinning deformation of {332}β〈113〉β and the ωiso phase during aging treatment. The Ti–15Mo alloy exhibits a small springback after ST and CRA treatment.
