Tungsten fiber reinforced Zr-Ti-Cu-Be-Co bulk metallic amorphous matrix composite was fabricated by a pressure infiltrating cast method. The deformation behaviors and mechanical properties were investigated. The results indicated that Tungsten fiber reinforced bulk metallic glass matrix composite not only holds high strength of pure Zr-Ti-Cu-Be-Co bulk metallic glass, but also exhibits the strain of more than 900% higher than those of pure Zr-Ti-Cu-Be-Co bulk metallic glass. The compressive failure mode of the composite shifts from shear to the localized fiber buckling and tilting with the increase of the volume fraction of tungsten fibers. The increase in compressive toughness comes from the fibers restricting shear band propagation, promoting the generation of multiple shear bands.
