Foreign Research and Analysis on Strengthening Technology and Material Technology of Tungsten Alloy Piercing Projectile

For the dynamic plastic deformation properties of tungsten alloy which is used in the kinetic energy projectile,the strengthening technology and the technology of piercing projectile core material were presented. Development of new type of tungsten alloy composite,replacing depleted uranium alloy,development performance tungsten alloy material and the same or even more than depleted uranium alloy are the important directions of the current. This paper focused on the development of nano tungsten alloy penetrator,non crystalline tungsten matrix composite and single crystal or tungsten whisker should reinforce composite of projectile core materials.
