Classic and symmetric Taylor tests were carried out on sintered Tungsten alloys in order to determine the failure modes, deformation profiles and strain histories during impact. Two material types were considered ; one that exhibited brittle fracture, the other more ductility. Impact velocities of 200 m/s were used in classic Taylor experiments and 300-370 m/s in the symmetric Taylor experiments. It was found in symmetric experiments that the rods bent ; fracture strains of up to 7.5% were attained, much higher than those found in quasi-static experiments. Both materials exhibited brittle intergranular fracture. Angled impact faces were also considered.
