Title:
チタンベースのセラミック強化合金
Document Type and Number:
Japanese Patent JP6945370
Kind Code:
B2
Abstract:
A titanium based, ceramic reinforced body formed from an alloy having from about 3 wt. % to about 10 wt. % of zirconium, about 10 wt. % to about 25 wt. % of niobium, from about 0.5 wt. % to about 2 wt. % of silicon, and from about 63 wt. % to about 86.5 wt. % of titanium. The alloy has a hexagonal crystal lattice ± phase of from about 20 vol % to about 70 vol %, and a cubic body centered ² crystal lattice phase of from about 30 vol. % to about 80 vol. %. The body has an ultimate tensile strength of about 950 MPa or more, and a Young's modulus of about 150 GPa or less. A molten substantially uniform admixture of a zirconium, niobium, silicon, and titanium alloy is formed, cast into a shape, and cooled into body. The body may then be formed into a desired shape, for example, a medical implant and optionally annealed.
