Abstract:The compressive deformation behaviors of Zr-based metallic glass composites containing different tungsten fiber orientations were investigated. The angles (theta(f)) between tungsten fiber orientation and loading axial direction are 0 degrees, 15 degrees, 30 degrees, 45 degrees, 60 degrees, 75 degrees and 90 degrees, respectively. The results show that the strength, plasticity and the failure modes vary with theta(f). At theta(f) =0 degrees, the composite possesses the highest strength and the largest plasticity. When theta(f) >= are 45 degrees and 90 degrees, the composites show relatively low compressive strength and plasticity. At theta(f) >= 15 degrees, the composites fail in different shear modes. The composites fail by in-plane sliding at 0 degrees < theta(f) <= 45 degrees, while the composites fail by out-of-plane sliding at 45 degrees < theta(f) <= 90 degrees. (c) 2013 Elsevier B.V.
