Embodiment 1

[0026] W powder, Fe powder, and Ni powder are uniformly mixed according to the mass fraction of W93%, Ni4%, and Fe3% to form a mixed powder, and then mixed with a binder accounting for 1% of the mixed powder for granulation. This embodiment The mass fraction of each component of the binder used is 33% paraffin, 33% polyethylene, 33% beeswax, and 1% stearic acid, and is processed into a hemispherical shell in an injection molding machine. In the fixed-point pre-sintering furnace, pre-sintering is carried out, and the atmosphere is that the vacuum degree is lower than 8×10 -2 The vacuum atmosphere of Pa, the temperature is 1350 ℃, and the holding time is 2h. After the sintering is completed, it will be released after cooling down with the furnace; a spherical shell formed by buckling two tungsten hemispherical shells will be filled with zirconium metal in the spherical cavity of the spherical shell. The ball core is put into two tungsten hemispherical shells, and the two tungste...

Abstract

The invention relates to a spherical prefabricated destroying element with a double-layer composite structure. The spherical prefabricated destroying element with the double-layer composite structurecomprises a spherical shell made of a tungsten alloy and a spherical core which is made of pure zirconium metal and fills the spherical shell. The destroying forms of the spherical prefabricated destroying element are more diversified, the ignition and detonation after effect is relatively good. The invention further relates to a preparation method of the spherical prefabricated destroying elementwith the double-layer composite structure. The preparation method comprises the following steps of injection molding, assembly, pre-sintering and sintering. The preparation method is simple in process and relatively high in production efficiency.

Description

technical field [0001] The invention relates to the field of prefabricated fragments, in particular to a spherical prefabricated damage element with a double-layer composite structure and a preparation method thereof. Background technique [0002] Modern ammunition usually consists of a warhead, a projection part, a guiding or guidance part, and a stabilizing part. The warhead is the part of the ammunition that damages the target or completes the intended terminal effect. The mutilation warhead is one of the main types of the warhead. It mainly relies on the explosion of high-energy explosives to form a large number of high-speed mutilators, and uses the high-speed impact, ignition and detonation of the mutilators to damage the target. It can be used to kill living forces (people, animals), unarmored or lightly armored vehicles, aircraft, radar and missiles and other weapons and equipment. [0003] High-density tungsten alloy ball is the most penetrating damage element in t...
