Abstract
Official abstract text for this publication.
The invention relates to a ternary Titanium-Zirconium-Oxygen (Ti—Zr—O) alloy, characterized in that it comprises from 83% to 95.15 mass % of titanium, from 4.5% to 15 mass % of zirconium and from 0.35% to 2 mass % of oxygen, with said alloy being capable of forming a single-phase material consisting of a stable and homogeneous a solid solution of Hexagonal Close Packed (HCP) structure at room temperature. The invention further relates to a method for producing such alloy as well as preferred applications and utilizations thereof.
First claim
Opening claim text (preview).
1 . A ternary Titanium-Zirconium-Oxygen (Ti—Zr—O) alloy comprising from 83% to 95.15 mass % of titanium, from 4.5% to 15 mass % of zirconium and from 0.35% to 2 mass % of oxygen, with the alloy being capable of forming a single-phase material consisting of a stable and homogeneous a solid solution with Hexagonal Close Packed (HCP) structure at room temperature. 2 . The alloy according to claim 1 , characterized in that it has a yield strength greater than or equal to 800 MPa. 3 . The alloy according to claim 1 , characterized in that it has an ultimate tensile strength (UTS) of about or greater than 900 MPa. 4 . The alloy according to claim 1 , characterized in that it has a total ductility of about 15% or more. 5 . The alloy according to claim 1 , characterized in that it is of the single-phase type up to temperatures close to the beta transus temperature. 6 . The alloy according to any claim 1 , characterized in that it is biocompatible. 7 . A method for producing a ternary alloy according to claim 1 , characterized in that the starting product is a ternary alloy in a recrystallized condition, and in that it is cold-worked at room temperature in order to increase the mechanical strength thereof. 8 . The method according to claim 7 characterized in that the cold-working consists in cold-rolling. 9 . The method for producing a ternary alloy according to the claim 7 , characterized in that the cold-worked alloy is submitted to a heat treatment by heating the alloy at a temperature between 500° C. and 650° C. for a time from 1 minute to 10 minutes to restore the ductility of the alloy while preserving a high mechanical strength. 10 . The method according to claim 7 , characterized in that the cold-working reaches a reduction ratio ranging from 40% to 90%. 11 . (canceled) 12 . (canceled)
