Development Overview of Tungsten Alloy Penetrators Core Material

Nearly 30 years, due to the high density tungsten alloy used successfully in the kinetic energy penetrators, and significantly improves the armor-piercing power, the consumption of the alloy is increased significantly. Penetrators alloy materials development through the following stages: high-strength steel -WC Carbide - sintered tungsten alloy - deep processing of high-density tungsten alloy (deformation processing and heat treatment) - High-density tungsten alloy composites.
In 1976, the fourth generation of armor-piercing tungsten alloy bomb core material base developed. By the 1980s, some of the major countries of the world are on a dozen tanks and dozens of artillery equipped with a tungsten alloy penetrators, artillery caliber from 60mm to 125mm, the maximum weight of up to bomb core 4kg, and assembled using a variety of forms (eg overall, multi-block, plus steel sleeve, etc.). Since the study and improvement of the mechanical properties and ballistic performance of high-density tungsten alloy, coupled with the supply of tungsten raw materials continue to improve, some industry advocates tungsten can and should be used as the main material of armor-piercing bomb core.

High density tungsten alloy bomb core material for a long time focused on the alloy composition, powder metallurgy, heat treatment and deformation processing technology, but also inseparable from the scope of homogeneous material, it should be said to have made ​​gratifying achievements, the strength of the material is a major breakthrough. After 80 years, the overseas development of a variety of composite materials, such as complex 丝加基 plated material, composites infiltration wire (or fiber) composite powder (or wire) and matrix composed of uranium - tungsten composite materials and high density tungsten alloy fiber-reinforced composite materials.

Begins with a high density of armor-piercing tungsten alloy mid-1970s, only 15 years to complete from the state to the several stages of sintering heat treatment and deformation processing of state and other states of the replacement, and were in a different caliber and variety of shells successful application on the type of projectile.
