厚度和层间界面对Ti6Al4V钛合金抗弹性能的影响

Effects of target thickness and macroscopic interface on the ballistic performance of Ti6Al4V titanium alloy were investigated. The monolithic Ti6Al4V titanium alloy with thickness varied from 10 mm to 30 mm and the armor configurations of the double-layered (15+15) mm Ti6Al4V titanium alloy were normally impacted by the 12.7 mm AP. The results show that the ballistic performance increases with the increase of the target thickness. Significant improvement is observed when the target thickness varies between 15 mm and 20 mm, which is considered to be related to the failure mechanism involved. The 30 mm monolithic Ti6Al4V titanium alloy is more effective than the (15+15) mm double-layered Ti6Al4V titanium alloy, which is related to the fact that no shear strength exists on the macroscopic interface between the double-layered targets.
