Dynamic fracture strength of tungsten alloys generated with a round bar Charpy specimen impacted at velocity ranging from 25 to 160 m/s has been reported to increase with loading rate. For as sintered alloys, the Charpy energy reached 1150 J/cm2 at 145 m/s, which is about 4 times the conventional Charpy energy obtained at 5 m/s. The analysis of the main failure process does not provide an explanation...
