Anisotropic compressive deformation behaviors of tungsten fiber reinforced Zr-based metallic glass composites

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