Abstract

Nowadays, an increasing number of new materials are used in shaped charge liner (SCL). However, most current work is focused on the density and high acoustic velocity of the SCL raw materials in order to improve the penetration depth of the SCL. This paper is going to introduce a Fe-Al-Bi alloy used for the SCL starting from new consideration of by importing the concept of 9 pressed sintering. The alloy's matrix is Al. Core-shell structure particles which have ductile and tough Fe cores and hard Fe3Al shells evenly distribute on the matrix. This paper analyzes the SCL's continuous high-energy jet which is the core-shell structure particles covered by plasma state Al. The interaction between the jet and targets improve SCL's penetration diameter and depth. It has been improved, compared with traditional SCL, the Fe-Al-Bi alloy SCL has better penetration performance.
