Controlling diffusion in Ni/Al reactive multilayers by Nb-alloying

Abstract: Metallic reactive multilayers are known as high energy-density storage systems. Conventionally, these multilayers are tailored for high reaction rates with the purpose to achieve high maximum reaction temperatures and explosive-like behavior upon mixing. However, in some instances such as neutralization of biological hazards or chemical energy-storage systems, a low heat flow rate is desired. In the present work, we show that Nb-alloying presents an efficient approach to stabilize the as-deposited state and to… Show more

“…The accumulated energy can be released in an abrupt emission of light and heat when stimulated by an external source [31]. They usually comprise pure metals such as Al and Ni, and can be prepared by multiple synthesis methods, including sputtering, evaporation, ARB and electrodeposition [31,121,127,128,144,362,[365][366][367][368]. The release of energy in reactive multilayers can be initiated by several techniques, including mechanical loading, thermal heating, laser heating or electrostatic discharge [31,127,128,144,[365][366][367][368].…”

The ignition starts a self-propagating reaction that is characterized by a high-temperature wavefront that propagates through the multilayer, which then transforms reactants into products [121,127,128,144].…”
