Large-sized Zr-based bulk-metallic-glass composite with enhanced tensile properties

► We successfully produce the large-sized Zr-based BMG composite with 11 mm diameter. ► The composite with 6 mm diameter of the gauge section exhibits 6% tensile plasticity. ► The deformation process and work-hardening behavior of the composite are clarified. ► The precipitated β-Zr particles with different length scales are obtained using SSPS. ► The tensile plasticity is enhanced significantly by increasing the size of the β-Zr.
