Abstract

A group of multicomponent Ti-Cu-Ni(Cr, Fe, Co)-Sn-Ta(Nb) alloys were investigated in terms of the microstructure and the mechanical properties. A composite microstructure with a micrometer-sized dendritic bcc-β-Ti(RM) (RM = Nb, Ta) phase dispersed in a matrix was obtained. The TEM observation on the Ti60Cu14Ni12Sn4Ta10 alloy shows that the matrix is composed of a nano/ultrafine bcc-phase with the size of 50—100 nm which is isolated by a tetragonal-phase. The designed Ti alloy exhibit very high yield strength (1050—1472 MPa) and relative lower Young's modulus (67—105 GPa). Such combined properties, not easily achievable in previous Ti alloys, make these new designed Ti alloys promising candidates as biomedical materials.
