Abstract

Enhancement of plasticity in Ni-based injection cast bulk metallic glasses (BMGs) and metallic glass matrix composites (MGMCs) has been investigated. The injection-cast Ni₅₉Zr₁₆Ti₁₃Si ₃Sn₂Nb₇ BMG showed a significantly improved plastic region to failure of 6.5%, as compared to that of the injection-cast Ni₅₉Zr₂₀Ti₁₆Si₂Sn₃ BMG of 2%. The Ni₅₉Zr₂₀Ti₁₆Si₂Sn ₃ MGMC containing brass-fibers shows macroscopic plasticity after yielding, and the level of plastic strain increased to around 2% with increasing brass content up to 40vol.%, while monolithic warm-extruded Ni ₅₉Zr₂₀Ti₁₆Si₂Sn₃ BMG show no plastic deformation region. Present study shows that the plasticity of BMG can be improved by selecting proper BMG alloy composition or by introducing ductile reinforcing phase in the BMG matrix.
