Deformation and Fracturing of Tungsten Pseudoalloys with Nickel and Iron under Impact Loading

Experiments on shock-wave loading and spall fracture of tungsten alloys with nickel and iron have been carried out. The alloys have been shown to fracture along the iron–nickel bonding and not to involve tungsten particles. One-dimensional defects, supposedly of twin origin, have been detected in the tungsten alloy (95 wt % W) during shock wave compression. The greatest number of these defects have been observed close to the surface of the impact.
