title = "Investigation on the penetration performance and penetration mechanism of 93W alloys fragments",
abstract = "In this work it's aimed to investigate the penetration performance of three W alloys cylindrical natural fragments that have similar density but different strength and elongation at break. The ballistic impact experiments indicate that the penetration performance of fragments increases with the increase of their strength. The semi-empirical formula for residual mass of W alloys fragments is fitted and it shows that the residual mass increase with the increase of their strength and elongation at break, and the semi-empirical formula can be used as a reference for material design of penetrators with excellent penetration performance. The microstructure analysis shows that the fragments suffer a severe plastic deformation. The failure mode of fragments is plastic deformation failure, and the failure modes of cracks are mainly the cleavage fracture of W particles and the interfacial separation of W particles and bonding phase.",
