AbstractPenetration experiments were conducted for Zr-based metallic glass composites containing tungsten fibers with different diameters of 0.3, 0.5, 0.7, 1.0 mm to perforate homogeneous armor steel at velocity of (1270 +/- 40) m/s. Meanwhile their characteristics and depths of penetration were compared with those of tungsten alloy. Results demonstrate that under the same preparation condition, the diameter of the tungsten fiber is a critical parameter for penetration ability. Firstly, the curve of the diameter of the tungsten with the penetration depth is convex when it perforates ideally and the composite containing 0.7 mm tungsten fiber obtains the maximum penetration depth of 55 mm which is increased by 25% compared with that of tungsten alloy because the failure mode is adiabatic shear failure during the penetration similar to that of the depleted uranium alloy exhibiting a crater of 90 degrees at bottom. Secondly, the diameter of tungsten fiber influences the failure mode of the head of the composites significantly. With the increasing of the tungsten fiber diameter, the failure mode ranges from a composite failure mode that includes deformation, splitting, bending and crack to adiabatic shear failure and then it turns to composite failure mode again.
