A Review of Mechanical Alloying Powders: A New Choice for Evolution of Explosive Materials

Aluminum powder is added to explosive materials in order to increase heat release and produce a longer pressure pulse. However, Addition of metal powder causes long delays and slow combustion rates. Furthermore, the decrease in the detonation velocity caused by metal additives significantly limits the capability of producing sharp pressure pulses required for many applications. Currently, to solve this problem scientists use the nanopowder in explosive formulations. But using the nanopowder in explosive formulations has several limitations such as handling and sensitivity problems. Recently, the research of metal combustion has offered new type of metal-based high energy density materials prepared using mechanical alloying (MA). In this paper, these materials and their properties for novel energetic materials have been introduced.
