W-Ni-Fe合金药型罩的破甲特性

Penetration Performance of W-Ni-Fe Alloy Shaped Charge Liner

摘要:

为了研究W-Ni-Fe合金药型罩的射流特征及破甲特性，对W-Ni-Fe合金药型罩进行静破甲试验，采用X射线照相系统研究W-Ni-Fe合金药型罩的射流形成能力，并对侵彻后的靶板进行宏观及微观分析。结果表明，W-Ni-Fe合金药型罩能形成高速延性射流，虽然穿深较低但破孔孔径大。靶板微观分析表明，破孔表面射流残余多且形成了高硬马氏体区。XRD结果表明，射流与钢靶相互作用剧烈，在破孔表面形成了大量Fe0.95W0.05化合物。马氏体及化合物硬质相的存在使得射流能量横向耗散严重，这是造成W-Ni-Fe合金药型罩穿深低、破孔大的主要原因

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 Fe0.95W0.05 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
