High strength low cost titanium and method for making same

Abstract

A titanium alloy and method of making the same are provided. The alloy comprises one or more elements selected from the group consisting of chromium, iron, and manganese. In an as-cast condition, the alloy has a yield strength of at least about 135,000 psi, a tensile strength of at least about 155,000 psi and a percent elongation of at least about 5.0 percent.

Description

field of invention [0001] The present invention generally relates to titanium alloys, and more particularly, the present invention relates to novel titanium alloys and methods for their preparation, which can be prepared from recycled titanium. Background technique [0002] Titanium alloys have an attractive combination of physical and mechanical properties, making them ideal materials for applications requiring high strength, low specific gravity, and good corrosion resistance. However, titanium alloys are expensive to produce, which severely limits their applications. Extracting titanium from its raw material into a usable form requires many processing steps. Furthermore, because of its highly reactive nature, the refining process must be carefully controlled, which further increases manufacturing costs. As a result, titanium applications are generally limited to military vehicles, aircraft engines and air-frame components, chemical processing implements, and sports equi...
