ORNL and IperionX Are Developing Low-Cost Titanium Alloys for AM

IperionX has announced that it is collaborating with Oak Ridge National Laboratory in order to further develop low-cost titanium alloys for additive manufacturing. As part of a U.S. Department of Energy (DOE) approved user agreement, the two will be working at DOE’s Manufacturing Demonstration Facility (MDF) to evaluate and characterize IperionX’s titanium spherical powders as well as demonstrate the characteristics of parts made using the powders, notably for the transportation sector. It will also complement ongoing work that IperionX is doing to test flight critical parts on behalf of the U.S. Navy

IperionX is an American company that works on titanium processing technologies. Notably, it seeks to help move the world towards a closed-loop, low-to-zero carbon, resource efficient and socially inclusive green economy. It focuses on titanium as it is critical to a number of industries thanks to the fact that it has the highest strength to weight ratio of all known metals, is naturally resistant to corrosion and has a higher melting point than aluminum, steel and iron. The company has developed a process that enables the production of low-cost titanium metal from titanium minerals or scrap titanium metal. This commitment to zero-waste creation of powder fits well with both the goals of the ORNL, who among other projects has been researching ways to commit to cleaner manufacturing in the US, and with additive manufacturing. In fact, 3D printing is often chosen for projects centered on closed-loop manufacturing thanks to its ability to reuse material as well as prevent unnecessary waste. Now this collaboration seeks to advance the applications of IperionX’s low-cost titanium alloys which have been created specifically for AM.

Developing Low-Cost Titanium Alloys for Additive Manufacturing

IperionX will be working with ORNL to achieve a number of objectives. Notably, they are hoping to show that the characteristics of parts made using sintering and IperionX’s low-cost titanium alloys and find opportunities to use the powders in parts that might be made with other metals such as stainless steel and aluminum. Additionally, sintered parts produced by IperionX’s Ti-6AI-4V alloy will be tested in order to ensure they meet the necessary proprerties for light-weighting in the transportation sector. These could then be used in heavy trucks, aircraft components or as part of IperionX’s ongoing work with the U.S. navy to test titanium flight critical metal replacement components in a project with the U.S. Department of Defense.
