It has been proposed that formation of adiabatic shear bands in WHAs could be promoted by the presence of stress concentrations. When different specimen geometries were tested, cylindrical specimens without geometric stress concentrations were the least prone to shear band formation. Shear bands tend to form at these initiation points and travel along the directions of greatest shear stress. Several WHA processing methods have been investigated to increase the propensity for shear band formation. Leveraging hot-hydrostatic extrusion and/or hot torsion has been shown to elongate the tungsten grains in the microstructure. When subjected to high strain rate deformation parallel to the direction of the grain elongation, adiabatic shear bands readily form and propagate along the Ni-Fe matrix phase. The flow stress of the matrix is much lower than that of tungsten, so texturing of the microstructure provides an easier path for propagation of shear bands.
