Interface of W fiber reinforced ZrTiCuNiBeNb bulk metallic-glass matrix composite

W fiber reinforced ZrTiCuNiBeNb metallic-glass matrix composite was prepared by melt infiltration casting. The interface structure and mechanical properties were analyzed by using XRD, SEM, EPMA and Nano Indenter MPM (mechanical properties micro-probe). The results illustrate that the interface of ZrTiCuNiBeNb metallic-glass matrix composite is a simply diffusion-dissolution layer only and there is no interfacial reactions between W fibers and matrix. The composite is included as a class II system according to the theory of interfaces in metal matrix composites. The hardness and elastic modulus of the interface are higher than those of the matrix. The interfacial bond is very strong and there isn't propagation of the cracks along the interface.
