A new tungsten heavy alloy with hybrid structure was manufactured for the kinetic energy penetrator. The tungsten heavy alloy is composed of two parts: core region is molybdenum added heavy alloy to promote the self-sharpening; outer part encompassing the core is conventional heavy alloy to sustain severe load in a muzzle during firing. The fracture surfaces of the specimen is observed after ballistic tests. The core region revealed brittle behavior with W/W inter-granular fracture which activates self-sharpening. On the other hand, outer part exhibited conventional ductile fracture mode. From ballistic test, it was found that the penetration performance of the hybrid structure tungsten heavy alloy is higher than that of conventional heavy alloy. This heavy alloy is thought to be very useful for the penetrator in the near future.

Long Rod

In this study, we analyzed the relation between mechanical and ballistic properties of several engineering ceramics that were expected to be used as armor materials. After the measurements of mechanical properties (Young's modulus, density, hardness, flexural strength and toughness), we measured the ballistic properties against a long rod KE projectile ( L / D =10.7, Kinetic Energy, tungsten heavy alloy) and copper jet projectile (40mm shaped charge warhead). The ballistic properties were generally increased as the increasing ratio of mechanical properties and density. As the HEL/density ratio was increased, it especially appeared that the ballistic properties were lineally increased.

Application Prospects

Due to the excellent physical and chemical characteristics and mechanical properties of the tungsten heavy alloy (WHA), the WHAs have been widely applied in many areas of the national economy. In this paper, the concept of the WHA is introduced briefly, and the preparation process and properties of the WHAs are summarized. Compared with depleted uranium alloy, the WHA shows broad application prospects in the field of kinetic energy projectile.

The Real

The failure mechanism of tungsten matrix composite was studied with microscale numerical simulation. The results show that high strength tungsten particles are the real loading elements of composite, its strength level embodies the whole property of the composite to some extent. The real stress in tungsten particles is much higher than the external load, so failure may take place when the external load is less than the theoretical strength of tungsten particles.
