Enhancement of plasticity in Ni-based injection cast bulk metallic glasses (BMGs) and metallic glass matrix composites (MGMCs) has been investigated. The injection-cast Ni59Zr16Ti13Si3Sn2Nb7 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 Ni59Zr20Ti16Si2Sn3 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 40 vol.%, while monolithic warm-extruded Ni59Zr20Ti16Si2Sn3 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. (C) 2004 Elsevier Ltd.
