摘要： The invention relates to a method for producing a penetrator (10) from a tungsten heavy metal with a high fraction of tungsten and an outer sheath (7), which consists of a material that is more ductile in relation to the penetrator core (6). To produce a penetrator (10) of this type in a cost-effective manner, according to the invention a twin-hopper filling device, which corresponds to the dimensions of the penetrator core (6), is introduced concentrically into a compression mold (1) that corresponds to the outer dimensions of the penetrator (10). The inner pipe (3) is filled with a first tungsten powder blend with a high fraction of tungsten for producing the penetrator core (6), while the annular gap between the outer wall of the inner pipe and the inner wall of the compression mold (1) is filled with a second tungsten powder blend with a lower fraction of tungsten, (approximately between 85% and 91%), than the first powder blend. Once the inner pipe (3) has been removed from the compression mold (1), the powder blend is then compressed in the known manner to produce the penetrator (10), the compressed body is subsequently sintered and cold-formed and the penetrator slug is finally finished.

摘要： A sub-caliber, spin stabilized multi-purpose projectile (FAPDS) made of a liquid phase sintered heavy metal sintered material composed essentially of metallic tungsten powder with additives of cobalt and nickel. To attain the highest final ballistic performance in lightly armored air and ground targets (e.g. aircraft, helicopters, armored personnel carriers) the present invention provides that the tungsten percentage of the projectile body lies between 90 and 99.5 weight percent, the density of the sintered material lies between 17.5 and 19.2 g/cm.sup.3 and the ratio of cobalt to nickel in the binder phase lies between 1:0.5 and 1:2.3, preferably 1:1.5. The projectile body according to the preferred embodiment of the invention is made of one piece and includes in its front portion a cylindrical pin for fastening of a projectile tip made of heat treatable steel. While ensuring stability during loading and firing, the projectile exhibits a highly sensitive, brittle matrix which develops in the sintered material only after the appropriate thermal treatment so that the projectile body, upon impact on the target, completely disintegrates upon encountering the slightest resistance and develops an optimum fragmentation effect.
