Microstructures and mechanical properties of as-cast TiCuFeC alloys for biomedical applications

摘要

Microstructures and mechanical properties of the TiFeCuC alloys are studied by adding The Fe96.8C3.2 (at. %) master alloy to the 5 at. % Cu containing titanium alloys. The microstructures and the mechanical properties are closely correlated with the content of the Fe96.8C3.2 master alloy. The TiFeCuC alloys show high strength and good ductility upon compressive test. The hypereutectic alloy Ti-70(Fe96.8C3.2)(25)Cu-5 presents the yield strength of 1962 MPa, the strain of 10.14% and the young's modulus of 166.6 GPa. The Ti-85(Fe96.8C3.2)(10)Cu-5 alloy presents the yield strength of 1108 MPa,the strain of 35.30% and young's modulus of 66.8 GPa. (C) 2018 Elsevier B.V. All rights reserved.
