| Abstract Scope |
The development of advanced metallic biomaterials has motivated the design of low-cost, non-refractory multicomponent alloys for orthopedic applications. In this study, Ti44Zr26Nb13Ta3Fe6Mn4Al4, Ti42Zr26Nb16Fe6Mn6Al4, and Ti42Zr22Nb20Fe6Mn6Al4 alloys were developed and characterized. The alloys exhibited a predominantly BCC structure with secondary precipitation of the C14 Laves phase. Microstructural analyses revealed dendritic morphologies with TiNb-rich BCC and ZrFeMnAl-rich C14 regions. Mechanical characterization showed a favorable combination of high microhardness (~420 HV) and reduced elastic modulus (~90–100 GPa), desirable for mitigating stress shielding. Electrochemical tests demonstrated the formation of stable passive films, with Ti42Zr22Nb20Fe6Mn6Al4 exhibiting corrosion resistance comparable to Ti-6Al-4V. Tribocorrosion results indicated enhanced resistance to the synergistic effects of wear and corrosion. Preliminary in vitro assays confirmed adequate cell adhesion and viability after 24 h. Overall, Ti42Zr22Nb20Fe6Mn6Al4 showed the most promising balance of mechanical, electrochemical, tribological, and biological properties for bone implant applications.
