Study on high temperature processing of biocompatible Ti-10Ta-10Nb alloys
Specimens of Ti-10Ta-10Nb have become hot forging after being heated to the state of α + β or â-phase. Various temperatures (650, 700, 750, 800, 850°C) and strain rates (0.001, 0.01, 0.1, 1, 10 s −1 ) are used. Based on the flow stress data from temperatures and compressive strain rates, a processin...

Zusammenfassung: | Specimens of Ti-10Ta-10Nb have become hot forging after being heated to the state of α + β or â-phase. Various temperatures (650, 700, 750, 800, 850°C) and strain rates (0.001, 0.01, 0.1, 1, 10 s

) are used. Based on the flow stress data from temperatures and compressive strain rates, a processing map was developed. Processing efficiency is high below about 0.1 s

of strain rates and at almost all the temperatures, but reduced at 0.001 s

and 800°C because of the occurring of Shear band. Processing methods for optimal process are summarized on the basis of experimental findings. Bio-compatibility experiments indicated that Ti-10Ta-10Nb alloy is better than the control, Ti-6Al-4V alloy. |
