Abstractβ-type titanium alloys have been developed all over the world, which widely used in several biomedical applications because of their good mechanical properties such as low Young’s modulus and corrosion resistance [1]. Niinomi et al. has also developed a β-type Ti-29Nb-13Ta-4.6Zr, referred to as TNTZ, which is composed of non-toxic and non-allergic elements such as Nb, Ta, and Zr, with low Young’s modulus [2]. It was also revealed that the cell viability on TNTZ is much superior than that on Ti-6Al-4V ELI [2,3]. Young’s modulus of TNTZ subjected has been found to be around 60 GPa at the microstructure having single β (BCC) phase for solution treatment and cold rolling [4-5]. It is much more closer to those (10-30 GPa) of bone than those (100 and 110 GPa) of commercial pure Ti and Ti-6Al-4V ELI.
