Nanostructured Ti-based multi-component alloys with potential for biomedical applications

A group of Ti60Cu14Ni12Sn4M10 (M=Nb, Ta, Mo) alloys was prepared using arc melting and copper mold casting. The as-prepared alloys have a composite microstructure containing a micrometer-sized dendritic β-Ti(M) phase dispersed in a nanocrystalline matrix. These new alloys exhibit a low Youngʹs modulus in the range of 59–103 GPa, and a high yield strength of 1037–1755 MPa, together with large plastic strains. The combination of high strength and low elastic modulus offers potential advantages in biomedical applications.
