Tungsten Alloy Applied for Warhead

Tungsten alloy warhead is well-known in military field now. You know, warhead is a very important component of armor-piercing projectiles, rocket projectiles, and missiles that can kill and destroy enemy weapons and equipment, facilities, and enemy effectives. Tungsten alloy is widely used in various warhead materials because of their unique properties, such as high density, high melting point, high strength, and good machinability.

In the application of tungsten alloy for warheads, some researchers have found that coarse-grained tungsten alloy is not sensitive to strain rate during tough-brittle transition, while ultrafine-grained tungsten alloy is not sensitive to strain rate. Some researchers believe that the ductile-brittle transition of coarse-grained tungsten alloy is controlled by the movement of screw dislocations, while the toughness and brittleness of ultrafine-grained tungsten alloy may be related to the movement of edge dislocations. Other researchers have used ultra-fast discharge plasma sintering method after ball milling to prepare ultrafine-grained tungsten alloy with a grain size of 130 nm. The hardness can reach 12 GPa and the dynamic impact strength is 4.14 GPa.
