The complex Al/CuO self-propagating reaction involving multi-phase and multi-species dynamics was studied in order to investigate the very high flame temperature around the vaporization temperature of alumina, even under a neutral environment. Experiments were performed on different sputter-deposited Al/CuO multilayers coupling optical...

Sputter-deposited Al/CuO multilayers capable of highly energetic reactions have been the subject of intense studies for tunable initiation and actuation. Designing high performance Al/CuO-based initiator devices definitively requires reliable prediction of their ignition and reaction kinetics including self-heating or aging as a function of...

Sputter-deposited Al/CuO multilayers exhibit fast combustion reactions in which an exothermic chemical reaction wave -controlled by the migration of oxygen atoms from the oxide matrix towards the aluminum layers through interfacial layers- moves throughout the multilayer at subsonic rates (m/s to tens of m/s). We directly observed the...
