Effect of tungsten fiber diameter on the dynamic compression properties of tungsten fiber/Zr-based bulk metallic glasses matrix composite

•WF diameter has no direct effect on the dynamic compressive strength of WF/Zr-MG.•WF/Zr-MG exhibits splitting failure and compound failure during dynamic compression.•Failure mode of WF/Zr-MG is affected by the volume fraction of WF and strain rate.•The initiation and propagation of cracks are not impeded by the fiber/matrix interface.
