Cu-based and Zr-based bulk metallic glasses matrix/tungsten fiber composites were produced by infiltration process at different temperatures and times. A characterization based on X-ray diffraction (XRD) and scanning electron microscopy (SEM) is presented. The composites were tested in compression and hardness. The quality of bulk metallic matrix composites is not only experienced by the properties of the matrix and reinforcement but also by the controlling of the infiltration conditions, such as infiltration temperature and time. These parameters are important for wet-ability and interface reaction of the liquid with the reinforcement. It has been found that the reaction layer cannot be detected between the wires and matrix for Cu-base BMGCs; this may be an important difference between Zr-base and Cu-base BMG matrices and their deformation mechanism.
