High-strength metastable beta-titanium alloys for biomedical applications

Aging at 482°C and above had little effect on either the microstructure or tensile properties of Ti-35Nb-7Zr-5Ta-0.06O. In contrast, the aging of Ti-35Nb-7Zr-5Ta-0.46/0.68O at 482°C for 8 h resulted in the formation of fine α precipitates with some evidence for precipitate-free zones associated with...

Zusammenfassung:Aging at 482°C and above had little effect on either the microstructure or tensile properties of Ti-35Nb-7Zr-5Ta-0.06O. In contrast, the aging of Ti-35Nb-7Zr-5Ta-0.46/0.68O at 482°C for 8 h resulted in the formation of fine α precipitates with some evidence for precipitate-free zones associated with prior β grain boundaries. These conditions resulted in an approximate 13% and 19% increase in yield strength when compared to the solution-treated condition.
