Damage Characteristics of Steel Targets Penetrated by Cu-Ni-Al and Cu Shaped Charge Jets

  • 摘要: 为了对比分析Cu-Ni-Al反应聚能射流和惰性Cu聚能射流对45钢靶的宏观侵彻特性和靶板的微观组织特征,分别进行了Cu-Ni-Al和Cu药型罩的侵彻实验,并利用光学显微镜、扫描电镜、能量色散光谱仪和Vickers显微硬度测量系统对回收钢靶进行表征。实验结果表明:Cu-Ni-Al反应射流对45钢的穿深与Cu射流相比明显降低,但其平均入口孔径提高了33.3%。两种聚能射流侵彻作用下钢靶中均存在残余射流区、白色区(马氏体和奥氏体的混合物)和变形区。与Cu射流相比,Cu-Ni-Al反应射流孔壁残余射流区的硬度值提高了34 MPa,孔壁尾部白色区的硬度值增加了95 MPa,其孔壁头部白色区的硬度值降低了28 MPa。两种聚能射流孔壁尾部白色区的硬度值均高于头部。研究结果可为评估反应材料药型罩聚能装药战斗部的毁伤效应提供一定的参考。
