  1. Step 1 Aging treatment • Ti-29Nb-13Ta-4.6Zr (TNTZ) • Low young’s modulus (E=60 GPa) • No toxicity and allergic elements • Good biocompatibility • Mechanical properties < Ti-6Al-4V Precipitationstrengthening Mechanical propertites Young’s modulus Step 2 particle (TiB, Y2O3) dispersion Dislocation pinning Structure refinement Effects of rare earth oxides on mechanical properties of Ti-29Nb-13Ta-4.6Zr alloy for biomedical applications Improvement of mechanical properties!

  2. Xiu Song Materials and methods • TNTZ • TNTZ- 0.05~0.5 B • TNTZ- 0.05~1.0Y Purpose Y2O3and TiB2 were added to TNTZ in the present study, in order toachieve excellent mechanical performance, and lower Young’s modulus. Young’s modulus X-Ray diffraction Tensile property Microstructure Vickers hardness Fatigue property
