Abstract

This proposal describes the development of a continuous process for the direct manufacture of low cost titanium alloy powders. The process will be an extension of a process, already under development by ITP, which produces pure titanium powder by reacting titanium tetrachloride vapor with a flowing liquid sodium stream. The alloys will be produced in the same equipment by replacing the titanium tetrachloride vapor with a mixture of vapors of volatile compounds of the alloy constituents. This project will concentrate on the production of Ti-Al-V alloys using a mixture of titanium chloride, aluminum chloride and vanadium chloride vapors. The alloy powder will be separated from the sodium and other reaction products, dried, packaged and sent to outside laboratories for chemical analysis, tests to measure particle size and Scanning Electron Microscope photographs to characterize the powder morphology. Metallurgical labs will test the powder behavior in powder metallurgical applications and will prepare solid tensile test specimens for the measurement of yield and ultimate strengths and elongation. This process will produce titanium alloy powder at a low enough cost that it can be used either as a melt feed stream to produce low cost ingots or to extend the range of powder metallurgical applications to low cost parts. Titanium alloys will cost less in current applications and penetrate whole new markets.
