    摘要:

    為了研究W-Ni-Fe合金藥型罩的射流特征及破甲特性，對W-Ni-Fe合金藥型罩進行靜破甲試驗，采用X射線照相系統(tǒng)研究W-Ni-Fe合金藥型罩的射流形成能力，并對侵徹后的靶板進行宏觀及微觀分析。結(jié)果表明，W-Ni-Fe合金藥型罩能形成高速延性射流，雖然穿深較低但破孔孔徑大。靶板微觀分析表明，破孔表面射流殘余多且形成了高硬馬氏體區(qū)。XRD結(jié)果表明，射流與鋼靶相互作用劇烈，在破孔表面形成了大量Fe0.95W0.05化合物。馬氏體及化合物硬質(zhì)相的存在使得射流能量橫向耗散嚴重，這是造成W-Ni-Fe合金藥型罩穿深低、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
