Abstract
Infrared processing is a newly developed technique for materials processing. Key features include rapid processing, simplicity, and low cost. Because of the rapid processing, very little oxide forms on the surface of parts. Thus, a vacuum is not normally required. Using infrared infiltration, aluminum- and titanium-matrix composites have been prepared under an ambient argon atmosphere. Using infrared bonding, carbon/carbon composites, titanium-matrix composites, titanium alloys, intermetallic compounds, nickel-based superalloys, and steels have been joined without vacuum requirements. Infrared bonding for parts up to 1.27 cm thick is typically completed in 30 seconds to two minutes. Because of rapid processing, there are few microstructural or property changes in the base materials after joining.
