Abstract

A series of Ti-Zr-Nb-Cu-Be metallic glass matrix composites with β-Ti(Zr, Nb) dendrites were synthesized by the copper-mold injection casting. The effects of the components on the size and volume fraction of dendrites were studied, and the mechanical properties of the samples were also investigated. The results show that Ti₄₈Zr₂₀Nb₁₂ Cu₅Be₁₅ performs good mechanical properties with compressive strength of 2061 MPa and plasticity up to 22.5%. The plasticity of metallic glass matrix composites is not only determined by the volume fraction of dendries, but also by the size of dendrites. The larger the dendrites, the more obvious for the resistance of moving shear bands, and the much higher plasticity of the alloy.
