摘　　要：利用靶试及数值计算研究钨丝增强锆基非晶弹芯侵彻弹坑形貌及直径,并进行理论分析。结果表明:钨丝增强锆基非晶弹芯侵彻弹坑较93W合金弹坑细长,且弹坑底部更尖锐。在稳定侵彻阶段,钨丝增强锆基非晶弹芯侵彻弹坑平均直径为10.1 mm,较93W合金弹坑小8.2%,这归因于钨丝增强锆基非晶动态压缩强度更高,侵彻过程具有"自锐"特性。The morphological characteristics of the penetration crater of ungsten wire reinforced zirconium based amorphous matrix composite were studied by ballistic experiment and numericalcalculation,and the theoretical analysis was carried out.The results show that the penetration crater of Wf/Zr-based amorphous matrix composite is slender than that of 93 tungsten alloy,and the diameter of the bottom of the crater is sharper.Meanwhile,the average diameter of the crater of the Wf/Zr-based amorphous matrix composite core is 10.1 mm,which is 8.2%smaller than that of 93 tungsten alloy in the stable penetration stage.This is attributed to the high dynamic compressive strength of Wf/Zr-based amorphous matrix composite and the self-sharpening property of this material during penetration.
