Abstract:
Dynamic shear properties of the tungsten heavy alloys containing 90% to 97% W (mass) were investigated using a hat-shaped specimen on the Hopkinson rod of Split Compression at a shear strain rate of 105 s-1. The results show that the dynamic shear strength increased and the shear strain decreased with the tungsten content increasing. The shear strength increased linearly with the increase of volume fraction of tungsten particles in the alloys. The shear fracture surface mainly exhibits tungsten grains split and matrix phase rupture, and the split proportion of tungsten particles equaled approximately to the volume fraction of tungsten particles.
