Abstract: Munitions structures comprising one or more high strength reactive alloys, in particular reactive bulk metallic glasses, have significant amounts of inherent chemical energy. This energy may be discharged by subjection of the munitions structure to rapid impulsive loading and fragmentation in the presence of oxygen and/or nitrogen. A munitions structure can be configured in both large and small penetrators, e.g. warheads and bullets, with increased lethality. The lethality of these munitions structures is augmented by means of rapidly and simultaneously imparting both mechanical energy (kinetic energy through impact and fragmentation) and chemical energy (blast and/or fireball) to a target. A high-strength reactive alloy can substitute at least in part one or both of explosives and inert structural materials in conventional munitions systems to improve performance and reduce parasitic weight of structural casing.

Abstract: A process for producing a munitions structure includes combining two or more transition metals including one or more of Zr, Hf, Ti, Ta, or Nb, and one or more other elements as alloying additions. The process further includes heating and fusing together the two or more transition metals and the one or more alloying additions to form a homogenous molten alloy. The homogenous molten alloy is cooled in a metallic mold to form a solid object with a desired shape for the munitions structure.
