Development Process of GW Series High-Density Tungsten Alloy

During the 1970s and 1980s, China's development and stereotypes produced three high-density tungsten alloy, and passed technical appraisal, armor-piercing bomb core material obtained as a successful application.

1.GW-1 alloy

GW-1 alloy is developed based on domestic raw materials for the first generation of tungsten alloy bomb core material, its main features are: (1) adding a small amount of elements made ​​of reinforced multicomponent alloys in W-Ni-Fe system, make this alloy has good sintering properties, no significant deflection after sintering, without the need for additional post-processing can achieve certain mechanical properties. (2) liquid-phase sintering process using powder metallurgy and easy process. (3) has good mechanical and physical properties, its main performance and the level of foreign alloy is quite similar, and has good machining properties.

GW-1 alloy from research to production in less than five years, the formation of the first generation of tungsten alloy bomb core material to fill the gaps in our tungsten alloy penetrators, laying the development of high muzzle velocity, high chamber pressure tungsten alloy armor-piercing bomb core material basis.

2.GW-2S high-density tungsten alloy

GW-2S alloy developed in the first generation of tungsten alloy penetrators on the basis of material up a high-density, high ductility, moderate strength alloys, it is to meet the high muzzle velocity, armor piercing high chamber pressure conditions in the semi-steel sleeve By using and developed a bomb core material. High density tungsten alloy can be heat treated, especially the use of vacuum heat treatment can improve the strength and ductility. But studies show that this heat treatment is only within a certain range of alloy composition to achieve good results. For this reason, studied the relationship between the heat treatment changes in Ni / Fe ratio, the further adjustment of the various process parameters to obtain a GW-2S alloys.

3. GW-3S high density tungsten alloy

With the high muzzle velocity kinetic energy penetrators, high chamber pressure, large slenderness ratio, and rely entirely on the strength of bomb core material itself to withstand high-speed transmission and ensure the normal development of the direction of flight of armor-piercing tungsten alloy material with more demanding, not only have high strength and high toughness and have a good dynamic. To do this they developed a GW-3S alloys. Through research, the better the traditional powder metallurgy and metal processing technology combined with modern, more comprehensive use of advanced scientific and technological achievements, so that the GW-3S alloy has a major breakthrough in terms of strength properties.
