Why is it important?
The mechanical properties of Ti-Nb alloys and the origin of its low Young's modulus (E) are explained based on the individual contribution of the different crystalline phases in the real material. The averaged E reproduces the experimental Ti-Nb Young's modulus w-shaped curve. E-surface reveals highly anisotropic E values for all Ti-Nb phases.
Perspectives
Eβ exhibits values under 30 GPa along the [100] direction for Nb compositions larger than 12 at. %, suggesting that the orientational growth of a Ti-Nb alloy is important for the design of low-rigidity alloys, especially at small Nb concentrations. The outcomes of our study can be used as a guide for the design of novel low-rigidity alloys for biomedical applications
