A method comprising bonding a first substrate to a second substrate. The first substrate includes a layer of one or more pairs of reactive material. The method comprising triggering a reaction between the one or more pairs of reactive material and fragmenting the second substrate.

An ignition system includes a multi-metallic ignition body that has at least two metallic elements in contact with each other. The metallic elements define an ignition initiation temperature above which there is a self-sustaining alloying reaction. A fluorine-containing body is in contact with the multi-metallic ignition body. The metallic elements may include palladium or palladium-ruthenium and aluminum.
