Finite element method was used to explore particles volume fraction, particles strain hardening index, particles spacing and reticular structure influence on the strength and the ductility of the new amorphous alloy composite materials which was metallic glass composites (MGCs). The results show that with the increase of particles strain hardening index, strength and toughness of the composite material have greatly improved, increase of particles volume fraction, smaller particle spacing and mesh structure configuration will also make the toughness of the composite materials increased. All these will be contributed to designing good toughness of composites.
