摘要	An experimental study was conducted for W/Zr38Ti17Cu10.5Co12Be22.5 composite pole penetrators perforating 30CrMnMo steel plates at velocities between 1300 m/s and 1700 m/s, and the penetrators were compared with the tungsten alloy pole penetrators. It is found that the penetration characteristics of the composites are different from those of the tungsten alloy and the depleted uranium alloy. Firstly, under the high velocity penetration, the composites have the phenomena of the amorphous alloy gasification, the tungsten fiber outside of the penetrator buckling and fracture, and the backflow of part of tungsten fiber during the penetration process, so the penetrator keeps self-sharpening, and the penetration is deeper than that of the tungsten alloy. Secondly, because of the amorphous gasification, the tungsten fiber outside dynamic buckling and splitting occur, the stiffness of the penetrator declines, and the penetration bifurcates, so the resistance of the plate is asymmetric, and the ballistic bending appears, which reduce the depth of the penetration. Meanwhile, the backflow of tungsten fiber gashes the sidewall of ballistic, and then the high pressure gas from the amorphous gasification impacts the scratch, which will produce the perfoliate cracks, so it is beneficial to the second damage.
