英文摘要	W-f/Zr-based metallic glass composites containing four kinds of tungsten fiber with different diameters were prepared. Penetration experiments were taken to perforate homogeneous armor steel at velocity from 1000 m/s to 1600 m/s. The results demonstrate that both the diameters of the tungsten fiber and the impact velocity are critical parameters for penetration ability. Firstly, the crater diameter of War-based metallic glass composites is more than 10% smaller than that of tungsten, which illustrates that the War-based metallic glass composite keeps self-sharpening during the penetration process. Next, the failure mechanism of W-f/Zr-based metallic glass composite changes from adiabatic shear failure to the tungsten fiber buckling and back-flow due to the impact velocity increasing. The smaller the diameter of tungsten fiber is, the more stable the penetration process would be, because the stability of penetration is affected by the diameter of the tungsten fiber.
