Abstract

In order to study the jet and penetration performance of W-Ni-Fe alloy shaped charge liner (SCL), the W-Ni-Fe alloy SCL was subjected to static penetration experiments. The X-ray imaging system was used to study the jet forming ability. The macroscopic and microscopic phenomenon of targets was investigated. Results show that W-Ni-Fe alloy SCL can form ductility jet and the jet velocity is high, although penetration is lower, and the hole diameter is large. The microscopic analysis result shows that there is much residual jet on the surface of bullet hole and high hardness martensite is formed. The XRD result shows that the interaction is very severe between jet and steel target, and in the meantime much Fe_0.95W_0.05 compound is formed. The low penetration and large hole diameter about W-Ni-Fe alloy SCL is a main result of severe transverse energy dissipation of jet which is caused by martensite and intermetallic.
