Abstract
A titanium based, ceramic reinforced alloy ingot for use in producing medical implants. An ingot is formed from an alloy having comprising from about 5 to about 35 wt. % niobium, from about 0.5 to about 3.5 wt. % silicon, and from about 61.5 to about 94.5 wt. % of titanium. The alloy has a hexagonal crystal lattice α phase of from about 20 vol % to about 70 vol %, and a cubic body centered β crystal lattice phase of from about 30 vol. % to about 80 vol. %. The ingot has an ultimate tensile strength of about 940 MPa or more, and a Young's modulus of about 150 GPa or less. A molten substantially uniform admixture of a niobium, silicon, and titanium alloy is formed, cast into a shape, and cooled into an ingot. The ingot may then be formed into a medical implant and optionally annealed.
