Air defense, anti-radiation, anti-surface and other types of warhead commonly used fragmentation warhead, mainly rely fragment kinetic-kill goal. Fragmentation can effectively kill the target and hit the target speed when fragmentation is closely related to the shape and quality. Fragments of spherical tungsten alloy (tungsten beads) due to the high density, attenuation coefficient, strong armor-piercing capability, become anti-aircraft, anti-radiation, the main choice of object surfaces and other types of anti-fragmentation warhead design.

Tungsten alloy spherical fragments due to its large density, speed, and ability to maintain strong piercing has gradually become the preferred elements warhead damage, so characteristic of research piercing tungsten alloy spherical fragments have a very important value. For the past fragments piercing questions, mostly concentrated in the conventional projectile velocity (500m / s ~ 1300m / s) hit Steel Fragments of the armor-piercing experiments and mechanism study of a single homogeneous steel target under the target conditions, and most of that: the same bomb target under the condition, completely through the thickness of the target plate hit the target with increasing speed must increase. For high projectile velocity (1300m / s ~ 3000m / s) piercing, pressure close to or exceed the material strength, impact body and the target material presented liquidity. In addition, with the increase of the target hit rate, tungsten alloy finite thickness of the initial invasion of impactor plate erosion and fragmentation phenomenon occurs, have a greater impact on the piercing process. Thus, the specific quality tungsten alloy fragments of penetration and steel target body there is a limit.

High quality tungsten alloy penetrator is an important symbol of national materials technology development, but also an important material for high performance kinetic energy penetrators, the development level of the relationship to improve our level of equipment needed weapons and can win a local war. To this end, should address some of the issues and the actual needs of the existing form a highly systematic research institutions and complementarity in order to promote China's missile technology developed tungsten alloy material to low-input, high-yield, high-level and high-practical direction, to improve the overall performance of armor-piercing tungsten alloy materials.

With the development of a tungsten alloy penetrators material, we should pay attention to the five major areas:

Armor-piercing shells performance is the most important performance indicators tungsten alloy, especially playing a board study of the mechanism of action, while also strengthening research adiabatic susceptibility tungsten alloy materials; 2.in order to improve anti-aircraft missiles and armor-piercing capability of damage, materials and systems research through burning complex functional elastomer material is friable Bouncing tungsten alloy body should carry out; 3.high toughness tungsten composite armor piercing is an important development direction of future ultra high-speed kinetic energy penetrators should be further strengthened with ultra high-speed kinetic energy penetrators research body piercing tungsten composite material beam; 4.Although China is a country rich tungsten, but reserves are limited, should be strengthened tungsten alloy shells with tungsten scrap and waste recycling, and low consumption of raw materials technology research and development. 5.Our coastline is very long, for the defense of coastal areas to prevent salt spray, seawater and humid environment for armor-piercing tungsten alloy with corrosion problems have been on the agenda, for which there should be targeted to carry out bomb tungsten alloy corrosion protection technology research.

Tungsten round dropshot weight offers the advanced performance of tungsten at a great price. Tungsten round dropshot weight is very useful for feeling bottom compositions, especially when fishing muddy or sandy bottoms, and the increased hardness of their tungsten composition makes them much more sensitive than comparable lead weights.

Tungsten round dropshot weight is more compact than lead weight owing to the higher density of tungsten, they are also environmentally friendly as well, which is helpful for protecting our fisheries.

Preparation of military bullets, armor-piercing shells and other materials generally require a high-density, high strength, high temperature resistant, not easily deformed and other characteristics. The high-density tungsten alloy just to meet their individual requirements. Therefore, the preparation of technical studies tungsten alloys in the manufacturing of military ballistic aspect is particularly important.

Tungsten grain refinement become a new hot spot of high-density tungsten alloy research, using mechanical alloying (MA), prepared by condensation drying method, chemical vapor deposition method, spray drying, sol-gel method and other methods of pre-alloyed powder, and the use of appropriate process may be prepared by a very fine powder. Furthermore, the reaction process may be a spray-step synthesis of fine grain, multi-component, pre-alloyed tungsten-based alloy powder, the powder can be a tungsten-based alloy at a temperature well below the melting point of the binder phase sintered to high density.

MA process for preparing nanocrystalline tungsten alloy composite powder, by sintering atmosphere of hydrogen at atmospheric pressure and tungsten grain densification during sintering behavior grew, MA process for preparing nanocrystalline powders can promote densification, so that densification temperature reduced by about 100 ℃~ 200 ℃, when the solid-phase sintering temperature can be generally obtained 3μm~ 5μm grain size of fine grain high-strength alloy interface. They also nano-tungsten alloy injection molding studied, indicating that 1 350℃ ~ 1 450 ℃ solid phase sintering to achieve full density i.e., the final alloy grains is about 3μm, tensile strength greater than 1200MPa. Temperature and pressure can significantly improve green density, temperature and pressure radial contraction blank blank room temperature is less than the radial contraction, and temperature and pressure can improve the microstructure of tungsten alloy. Also, the use of pre-oxidized tungsten alloy activated sintering, the sintering temperature can be lowered to reduce the tungsten alloy deformed and obtain a dense tungsten alloy, and can improve the tensile strength and elongation of tungsten alloy.
