A new, potentially lower-cost approach for the production of advanced titanium and titanium-alloy materials has been demonstrated using cryogenic technology. The alloys produced have an ultra-fine grained structure, high-angle boundaries, and finely-dispersed particulates having near-nanometer-scale size. These features combine to impart excellent strength levels, good ductility, and excellent microstructural thermal stability. In addition, the powders are macroscopically in the micrometer range having pre-alloying capabilities. This feature allows for easy handling, cleaner surfaces, and no environmental dangers. This paper summarizes the preliminary results of the macrostructures, microstructures, chemistries, and mechanical properties achieved via the cryogenic processing.
