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 beta-Ti(M) phase dispersed ill a nanocrystalline matrix. These new alloys exhibit a low Young's 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. (C) 2003 Elsevier Ltd. All rights reserved.
