Abstract
A bulk metallic glass (BMG) material includes at least one high strength reactive alloy having a surface on which one or more surface features are formed. The one or more surface features are configured to at least partially control a fragmentation of the BMG material. The BMG material forms a cavity within which an explosive is configured to reside.
Claims20
A munition comprising:
- an explosive;
- and
- a munitions structure substantially enclosing the explosive and being formed from a high-strength reactive alloy, the munitions structure including;
- a first surface having one or more grooves, wherein the munitions structure is configured to fragment at least partially along the one or more grooves,
- a second surface at least partially forming a cavity in which the explosive is disposed,
- a first thickness extending between the first surface and the second surface, the first thickness being external to the one or more grooves, and
- a second thickness extending between the first surface and the second surface, the second thickness being internal to the one or more grooves, the second thickness being less than the first thickness.

A munitions structure comprising:
- a high-strength reactive alloy in a form of a bulk metallic glass (BMG) material, wherein the BMG material includes:
- a first surface having one or more grooves along which the munitions structure is configured to at least partially fragment,
- a second surface that at least partially defines a cavity in which an explosive is configured to reside,
- a first thickness disposed between the first surface and the second surface, the first thickness being at a location external to the one or more grooves, and
- a second thickness disposed between the first surface and the second surface, the second thickness being at a location within the one or more grooves, the second thickness being less than the first thickness.
