Abstract
Improved liners and explosive devices having improved liners are provided. In accordance with an exemplary embodiment, a liner for an explosive device comprises a plate configured to be positioned against an explosive charge. The plate comprises rhenium, palladium, or a combination thereof, at least a bimodal particle size distribution having a powder grain size no greater than 25 microns, a substantially circular diameter, and a substantially concave interior relative to a surface of the explosive charge.

A liner for a warhead, the liner comprising:
- a first plate configured to be positioned against an explosive charge of the warhead, a second plate coupled to the first plate, and an explosive disposed between the first plate and the second plate,
- the first plate comprising:
- rhenium, palladium, or a combination thereof;
- the first plate being formed of material having at least a bimodal particle size distribution and having a powder grain size no greater than 25 microns;
- a substantially circular diameter;
- and
- a substantially concave interior relative to a surface of the explosive charge the second plate comprising rhenium, palladium, or a combination thereof.
A liner for a warhead, the liner comprising a first plate configured to be positioned against an explosive charge of the warhead, the first plate comprising:
- a combination of palladium and rhenium in a ratio of about 3 to about 97 wt.% palladium:
- about 97 to about 3 wt.% rhenium;
- the first plate being formed of material having at least a bimodal particle size distribution and having a powder grain size no greater than 25 microns;
- a substantially circular diameter;
- and
- a substantially concave interior relative to a surface of the explosive charge.
A liner for a warhead, the liner comprising a first plate configured to be positioned against an explosive charge of the warhead, the first plate comprising:
- rhenium, palladium, or a combination thereof;
- the first plate being formed of material having at least a bimodal particle size distribution and having a powder grain size no greater than 25 microns, about 25% of particles of the first plate having a grain size in the range of about 100 to about 300 nm and about 75% of particles of the first plate having a grain size in the range of about 20 to about 75 nm;
- a substantially circular diameter;
- and
- a substantially concave interior relative to a surface of the explosive charge.
