  • Patent number: 5119729
    Abstract: A hollow charge for piercing armor built up of several layers of differing densities, the metallic lining of which has three-dimensional isotropy and the density of which corresponds at least approximately to the crystal density of the metal, and, upon detonation, produces an incoherent, pulverulent hollow-charge jet. The associated method of manufacturing the metallic lining comprises atomization of the metal; the mixing of the resulting metal powder in a broad particle-size distribution; the filling of the metal powder into a uniform thickness, double-walled, ductile container; hydrogen flushing of the filled-in metal powder, the closure and gas-tight sealing-off of the double-walled container; hot isostatic pressing of the container; and the removal of the sealed-off container from the pressure-molded component.
