A titanium alloy comprising an elevated level of oxygen is disclosed. The alloy may have 5.5 to 6.75 weight percent of aluminum, 3.5 to 4.5 weight percent of vanadium, 0.21 to 0.30 weight percent of oxygen, and up to 0.40% of weight percent of iron. The alloy may also have a minimum ultimate tensile strength of 130,000 psi, a minimum tensile yield strength of 120,000 psi, and a minimum ductility of 10% elongation. Also disclosed is a method for manufacturing components having the aforementioned alloy.

Oxygen-enriched Ti-6AI-4V alloy and process for manufacture

Titanium-tungsten alloys are described comprising tungsten ranging from about 9% to about 20% by weight, and titanium ranging from about 91% to about 80% by weight, exhibiting a yield strength of at least 120,000 psi, and a ductility of at least 20% elongation. Methods of making the alloy, and products made with the alloys are also disclosed herein.

Homogeneous titanium tungsten alloys produced by powder metal technology

Disclosed herein are extruded titanium metal matrix composites with enhanced ductility. Also disclosed is the extrusion at high extrusion ratio of titanium metal matrix composites produced by powder metal processes. The ductility and machinability of these titanium metal matrix composites extruded at high extrusion ratios combined with their wear resistance and excellent imaging characteristics makes these high extrusion ratio extruded titanium metal matrix composites useful as biological implants, including prosthetic devices. Also disclosed are articles such as orthopedic implants for knee, hip, spine or other biomedical devices, with enhanced properties, made from the disclosed extruded material.

High extrusion ratio titanium metal matrix composites

A method is described for producing a corrosion and mechanical wear resistant coating on a metal surface to be protected. The method comprises (a) providing a rod or wire formed of a metal matrix composite comprising a metal matrix having distributed therein a finely divided solid filler material and (b) applying a coating of said metal matrix composite on said metal surface to be protected by means of a flame spraying or arc spraying process. This results in a coating of improved adhesion and low porosity.
