Fracture and damage behaviour of tungsten alloy of 93W and 98W under explosive loading

The fragment mass, amount distribution and penetrating behaviour of 93 W and 98 W under explosive loading were investigated. The mass of 93 W fragments ranged from 0.1 g to 3.0 g. The mass and shape of 93W fragments are not well-distributed, but those of 98 W are. The mass of 98 W fragments has a concentrated distribution from 0.1 g to 0.5 g and over 98% of the fragment shapes are close to isoaxial. Failures at the tungsten-matrix interface are main on fragments of 93 W. However, 98 W fragments had a large proportion of transgranular cleavage.
