“…The Zr-effect on the β-phase stability was also reported for many low Zr-containing β-type alloys, such as Ti-Cr-Zr [8], Ti-Ta-Zr [9], TiNb-Zr [3,9], Ti-Nb-Ta-Zr [10] and Ti-Nb-Sn-Zr [11]. In the αþβ-type Ti-Al-Mo-Cr-Fe alloys, the Zr-effect on the β-phase stability was also reported [12]. However, no literature has reported the Zreffect on the β-phase stability in α-type Ti alloys.…”

“…Thereby Ti-Zr based alloys have an advantage in cost of manufacturing. Zr is known to be neutral element for Ti, 12) however, Abdel-Hady et al reported that Zr works as a ¢-stabilizing element in ¢-type Ti-Zr-Nb alloys and the ¢ stabilizing effect of Zr increased with increasing Nb content in the Ti-Nb-Zr alloys. 13) In current research, Ti-Zr based alloys contain 50 mol% Zr, this is quite unusual amount as additional element, therefore high amount of Zr contributes to emphasizing ¢ phase stabilization.…”

The influence of Nb addition on phase constitution, microstructure and mechanical properties of biomedical equi-atomic Ti-Zr based alloys was investigated. Phase constitution of Ti-Zr based alloys containing Nb rapidly cooled from ¢ single phase changed with Nb addition as follows:Young's moduli of Ti-Zr based alloys subjected to water quenching initially decreased with increasing Nb content. The minimal value was obtained in the Ti-48Zr-4Nb (mol%) composition alloy. The Young's moduli increased in relation to the phase constitution change. In the alloys containing over 4% Nb, their principal phase was changed by subsequent cold rolling, this is mainly because ¢ ¼ ¡A and ¢ ¼ ¡AA stress-induced martensitic transformation occurred. This phase transformation resulted in a decrease of Young's modulus. Furthermore, cold rolling impartd anisotropy to the Young's modulus which caused the value to drop. The Ti-47Zr-6Nb alloy had the lowest value of Young's modulus after cold rolling in this study, 59.5 GPa.
