Beta-type Ti-29Nb-13Ta-4.6Zr (TNTZ) has been developed as an attractive candidate for metallic biomaterial applications because of its unique combination of favorable mechanical properties such as high tensile strength and a low Young’s modulus of nearly 60 GPa and outstanding biocompatibility compared with the most widely used metallic biomaterials (alpha + beta-type Ti-6Al-4V etc.). In this study, mechanical performances of TNTZ subjected to heat treatments after plastic deformation or severe plastic deformation (SPD) were investigated in order to judge its potential for next-generation metallic biomaterial.
