| Abstract Scope |
Biocompatible alloying system with different content of Ti, Nb, Ta and Zr has been thoroughly studied in last two decades. The sufficient ammount of β stabilizing elements enable the alloys to retain pure bcc beta phase after quenching from the beta region, what is cruitial for low Young’s modulus. Their tensile strength can be increased by adding high content of interstitial oxygen atoms. In contrast, due to high electron per atom ratio of oxygen, Young’s modulus also increases. In order to find the best alloy composition, several alloys with 0.7 wt.% of oxygen and different Nb, Ta and Zr content were designed and fabricated. Microstructure and phase composition were studied by means of scanning electron microscopy. Mechanical properties at room temperature were determined by microhardness measurements and tensile testing. Multiple compositions showing low Young’s modulus were found, while maintaining sufficient strength and ductility. |
