XRD and nanoindentation testing of thermo-mechanically processed Ti-29Nb-9Ta-10Zr alloy

摘要

Ti-Nb-Ta-Zr alloys (TNTZ) represent a new class of biomaterials, due to nontoxic chemical elements and promising combination of high mechanical resistance with low elastic modulus close to the bone elasticity (E = 20-40 GPa). The present paper proposes a particular chemical composition of this 3 type Ti alloy Ti-29Nb-9Ta-10Zr (wt.%) with a particular material structure. Structural and mechanical characterization of four distinct alloy conditions corresponding to each TM stage was performed using XRD measurements and also nanoindentation measurements. The obtained results represent a solid base for complex optimization of the alloy's structural characteristics.
