Ti-Nb-Ta-Zr alloys for biomedical applications were successfully fabricated by arc melting (AM) and diffusion bonding.The microstructure,mechanical properties and electrochemistry behavior in a simulated body fluid (SBF) were studied.It shows that melted Ti-Nb-Ta-Zr alloy mainly contains β phase although there are a few Ti-rich phases and micropores,the number of which is lower than that in sintered sample with a few Ti-rich and Ta-rich phases.The melted alloys present higher strength (1224 MPa),Young’s modulus (15.3 GPa) and corrosion potential (-0.34 V) in SBF,while total recovery strain ratio (67.5％) and pseudoelastic strain ratio (8.4％) of sintered Ti-Nb-Ta-Zr alloy keep higher value than 35.7％ and 5.0％ for melted Ti-Nb-Ta-Zr.The reasons were discussed based on the microstructure of the Ti-Nb-Ta-Zr alloys.
