Al/Ni reactive multilayer systems (RMS) with a bilayer thickness of Λ=50nm and total thickness th=5μm on a SiO2 substrate exhibit a self-propagating reaction after ignition. A common method to initiate the self-propagating reaction is by electric spark ignition. In this work, RMS are ignited by a mechanical impact using various materials with indeterminate geometries to investigate the basic mechanisms.

1 Introduction So-called energetic materials inherently store a large amount of energy, mostly as chemical energy, and can show a fast and hot self-propagating exothermic reaction after ignition.[1-5] A well-studied class of such materials are reactive multilayer systems (RMS).[3-5] They consist of alternating thin layers of two or more elements. Systems like Pt/Al, Ti/B, Al/Ni, and more[6-8] have been developed and investigated over the last years.
