Nanoheater systems based on the exothermic reaction between aluminum and nickel were developed. Multilayered and powder-based heterostructures were fabricated and characterized, before and after ignition experiments, for their geometries and structures as well for the ignition and exothermic transformation kinetics. A novel ultrasonic powder consolidation (UPC) technique1 was employed to produce ignitable Al/Ni compacts from elemental powders. Oxide free, fully dense Al matrix and intimate Al/Ni interfaces were obtained. Consolidates were successfully ignited and the reaction self-propagated throughout the compact resulting in the formation of NiAl phase. The ignition characteristics of multilayered structures and sequential thermal generation and conduction were investigated by IR thermal camera measurements.
