Alternative alloys derived from the wide array of aerospace superalloys will be
developed for hot gas filtration to improve on both ceramic filters and
"first-generation" iron aluminide metallic filter materials. New high
performance metallic filters should offer the benefits of non-brittle mechanical
behavior at all temperatures, including ambient temperature, and improved
resistance to thermal fatigue compared to ceramic filter elements, thus
improving filter reliability. A new powder processing approach also will be
established that results in lightweight metallic filters with high permeability
and weldability for enhanced capability for filter system manufacturing.
