Shaped charge; Copper liner; Penetration depth.


This paper presents the penetration behavior of copper shaped charge liners produced by four different techniques, including deep drawing, deep drawing followed by metal spinning, SPS sintering and SPS sintering followed by metal spinning technique. The results show that the grain size of copper liners has a strong effect on the penetration depth into steel targets. The metal spinning step led to the appearance of the subgrains and the increase of dislocation density and hence, improved the penetration depth of the copper shaped charge liner. Accordingly, the penetration depth of the shaped charge liners produced by deep drawing followed by metal spinning and SPS sintering followed by metal spinning into steel targets reached the highest values, which are about 80 mm. Meanwhile, the penetration depth of the shaped charge using SPS sintered liner is 70.5 mm. The copper liner made by deep drawing produced an unstable depth and was about 50 mm. This work also shows the formation of the subgrains with a width in the range of 300 to 500 nm and a length from 1 to 3 mm in the liners microstructure after metal spinning.
