The fabrication and characterization of metal‐based energetic composite materials are currently being examined for a range of new applications. A newly developed ultrasonic consolidation process is used for the synthesis of Al/Fe 2 O 3 and Al/Cu 2 O compacts over a wide range of powder ratios at room temperature. Powder consolidation was achieved by a multistep procedure involving simultaneous application of pressure and ultrasonic vibrations. The observed reaction characteristics of the composites are similar to those of previously reported thermite compacts prepared by a traditional powder metallurgy method.
