Problems solved by technology

[0003] As a kind of kinetic energy weapon, if you want to obtain better armor-piercing effect, high-density projectile core is essential. At present, armor-piercing projectiles often use high-density materials such as tungsten alloy and uranium alloy as the projectile core. The radioactive pollution of uranium alloy will The human body causes great damage, but the density of tungsten alloy is not high enough and the self-passivation is high, so the penetration of the prepared armor-piercing projectile often needs to be improved

Embodiment 1

[0032] Such as figure 1 Shown, a kind of core preparation method comprises the following steps:

[0033] S10: Making tungsten alloy and / or elemental tungsten into projectiles, blocks, rods, wires or powders to obtain skeleton materials;

[0034] S20: Put the framework material into the mold cavity, and cover the surface of the framework material with alloy powder filler; the mass ratio of the framework material to alloy powder filler is not less than 3:1, and the alloy powder filler includes amorphous fillers and / or high-entropy alloy fillers;

[0035] S30: After evacuating the mold cavity, heat to 600-1400°C, stop heating after the alloy powder filler in the mold cavity is completely melted, and cool down, so that the alloy powder filler is solidified and completely embeds the skeleton material to obtain a composite core.

[0036] In detail, in this embodiment, the mold cavity has a spherical or spherical structure, the mass ratio of the skeleton material to the alloy powd...

Abstract

The invention discloses a bullet core preparation method. The bullet core preparation method comprises the following steps that a tungsten alloy and / or elemental tungsten is made into a bullet, a block, a bar, a wire or powder, and a framework material is obtained; the framework material is put into a mold cavity, and the surface of the framework material is covered with alloy powder filler; the mass ratio of the framework material to the alloy powder filler is not less than 3: 1, and the alloy powder filler comprises an amorphous filler and / or a high-entropy alloy filler; and the mold cavity is heated to 600-1,400 DEG C, heating is stopped after the alloy powder filler in the mold cavity is completely melted, cooling is conducted, the alloy powder filler is solidified to completely embed the framework material, and the composite bullet core is obtained. According to the bullet core preparation method, the framework material and the alloy powder filler in a reasonable proportion are compounded, after the alloy powder filler is quickly molten through heating, rapid cooling is conducted, an amorphous tissue structure is formed on the surface of the framework material, and the bullet core higher in breaking strength and hardness can be prepared easily.

Description

technical field [0001] The invention relates to the technical field of bullet core preparation, in particular to a bullet core preparation method and a composite bullet core. Background technique [0002] Armor-piercing projectile is a typical kinetic-energy projectile that penetrates armor depending on projectile strength, weight and speed. Modern armor-piercing projectiles have sharp warheads and slender projectiles. They are made of steel alloys, depleted uranium alloys, etc., and have extremely high strength. In modern warfare, the stronger the penetrating ability of armor-piercing projectiles, the greater the threat to the enemy. Therefore, how to improve the penetrating ability of armor-piercing projectiles has always been the research focus of researchers. The bullet core is the main body of the armor-piercing bullet, and the physical properties of the bullet core material directly determine the penetration performance of the armor-piercing bullet. Therefore, the tech...
