Alloy Phase and Microstructural Effect of Ti6al4v Eli and Ti13nb13zr Alloys on Titanium Dioxide Nanotubes (Tnt) Growth

Published: Jan. 1, 2025

Titanium dioxide nanotubes (TNTs) have drawn significant attention due to their prospective applications in osseo-integrative biomedical implants. Understanding the influence of alloy composition and phase distribution on TNT morphology, particularly nanotube length, is essential for optimizing these materials. In this study, we synthesized TNTs two titanium alloys, Ti6Al4V ELI Ti13Nb13Zr, investigate how distinct microstructures impact formation. Electron backscatter diffraction analysis revealed unique grain structures orientations. The microstructure depicted an equiaxed structure parallel (0001) α-plane while that Ti13Nb13Zr showed needle-like α-phase β-phase matrix. These microstructural differences were hypothesized enhance ion diffusion selective dissolution, promoting longer This work shows with average length 11.33 µm, significantly exceed 1.76 µm observed ELI. higher aspect ratio attributed its matrix, which facilitated migration during anodization. Electrochemical analyses, including Tafel polarization impedance spectroscopy, confirmed superior dissolution resistance supporting extended growth. properties make a good candidate use areas need high amounts surface area enhanced biocompatibility

Published: March 1, 2025

Beta-type Ti-Zr-Nb (TZN) medium-entropy alloys (MEAs) are being extensively investigated as orthopedic implants due to their metallic mechanical properties, corrosion resistance, and biocompatibility. However, improvements in elastic admissible strain, strength, ductility still needed ensure high performance clinical applications. In this study, we designed a series of negative mixing enthalpy MEAs by adding 0, 3, 5, 7, 10 at.% aluminum (Al) equimolar TZN alloy (denoted TZNAx (x = 7 10)). These were fabricated arc melting followed cold-rolling annealing, microstructure, wear biocompatibility systematically studied. general, the showed significantly improved strain strength-elongation product compared with those CP-Ti Ti64; particular, TZNA5 exhibited best combination properties an modulus ∼54.6 GPa, yield strength ∼1040 MPa, ultimate ∼1132 elongation ∼21 %.
