Abstract
The invention discloses a Y-shaped fragile tungsten-based material which comprises a tungsten-based material body. The tungsten-based material body comprises 85-95 parts of tungsten powder, 1-5 of parts tungsten particles, 0.5-3 parts of nickel powder, 0.5-3 parts of iron powder, 0.1-2 parts of cobalt powder, 0.3-1 part of molybdenum powder and 1-6 parts of alumina powder. The Y-shaped fragile tungsten-based material has the advantages that the characteristic of soft texture of a lead material is overcome, the penetrability is ensured, and the constraint of international regulations is avoided; compared with a traditional tungsten-nickel-iron alloy, the material has fragility on the premise of keeping the hardness of the tungsten-based alloy; and all component elements used in the materialare conventional materials, special materials are not needed, and the manufacturing cost is not increased.
Description
technical field [0001] The invention relates to the technical field of new materials, specifically a Y-shaped brittle tungsten-based material. Background technique [0002] The military put forward the following indicators for a new type of shotgun under research: 1. Self-injury protection for one’s own fighters, that is, when the bullet is fired at a muzzle velocity of 370-400 m / s for a distance of 5 meters, the projectile hits the reinforced concrete wall. Broken can not rebound. Two, the enemy must have lethality, that is, when the bullet is fired at a distance of 50 meters with a muzzle velocity of 370-400 m / s, the projectile will also penetrate a 25mm pine board. 3. The number of projectiles loaded in each bullet shall not be less than 20. [0003] Defects and deficiencies of the prior art: [0004] 1. Now there are bullets that do not bounce back, and the material is lead. Due to the soft nature of lead, projectiles made of lead will not rebound. However, lead has...
