Abstract

The surface characteristics of the AK-47 (7.62 mm x 39 mm Armour Piercing) and G3 (7.62 mm x 51 mm Armour Piercing) projectile tips were investigated after impacting an Al alloy reinforced with Al2O3 particles at high velocity. The composite samples were manufactured from Al-7075 by the squeeze casting method and they were subjected to ballistic impact tests as defined in related ballistic standards of the National Institute of Justice standards.
