Investigations on ballistic impact property of Ti-6Al-4V based armor configurations against 12.7 mm armor piercing projectiles

摘要：

　　In this paper, effect of target thickness, double-layering, and the order of layers on ballistic impact property of Ti-6Al-4V based armor configurations normally impacted by the 12.7 mm AP was investigated.The results showed that the increase in ballistic impact property for the monolithic Ti-6Al-4V targets is about 163 Pct when increasing the target thickness from 15 to 30 mm.The 30 mm monolithic Ti-6Al-4V target was more effective than the (15+15) mm double-layered Ti-6Al-4V targets.Since the order of layers affected the ballistic impact property of the (15+15) mm double-layered Ti-6Al-4V based configurations, the ballistic impact property was improved by about 49 Pct when the first layer was Ti-6Al-4V alloy with the RHA steel as the second layer.The differences in the ballistic impact property between various impact conditions can be related to the failure modes analyzed in the Ti-6Al-4V based armor configurations.
