    摘要： The invention is an explosively formed projectile (EFP). On detonation of an explosive charge, an explosively formed projectile is formed from two separate metal elements, an open-poled dished liner and a cavitation pin. The open-poled dished liner is made of a metal more dense than a metal of the cavitation pin. The cavitation pin lies on the open-poled dished liner longitudinal axis and in contact therewith. The cavitation pin has a truncated right conical shape with a base diameter to length ratio of 0.7:1 to 1.5:1. The ratio of the open-poled dished liner diameter:cavitation pin fore portion major base diameter is 2:1 to 4:1. Upon detonation, the cavitation pin leads the explosively forged liner in the explosively formed projectile assembly. The leading pin causes cavitation in water resulting in an increase in the velocity of the explosively formed projectile.

    摘要： A technique facilitates perforation, including the perforation of a casing and formation. A shaped charge is formed with a case, a liner, and a high explosive material located between the case and the liner. The liner is formed of a powder material, e.g. a powder metal material. The powder material properties of the liner between an apex of the liner and a skirt of the liner may be selectively varied to provide a desired jet velocity and jet mass of the liner upon detonation of the high explosive material.

    摘要： A binary or higher order high-density thermodynamically stable nanostructured copper-tantalum based metallic system according to embodiments of the invention may be formed of: a solvent of copper (Cu) metal that comprises 70 to 100 atomic percent (at. %) of the metallic system; and a solute of tantalum (Ta) metal dispersed in the solvent metal, that comprises 0.01 to 15 at. % of the metallic system. The metallic system is thermally stable, with the absence of substantial gross grain growth, such that the internal grain size of the solvent metal is substantially suppressed to no more than about 250 nm at approximately 98% of the melting point temperature of the solvent metal and the solute metal remains substantially uniformly dispersed in the solvent metal at that temperature. Processes for forming these metallic systems may include: subjecting powder metals of solvent and the solute to a high-energy milling process using a high-energy milling device to impart high impact energies to its contents. Due to their high-density thermodynamically stable nanostructured, these metallic systems are an ideal candidate for fabricating shaped charge liners for ordinance.
