Fabrication of Ni-Nb-Ta metallic glass reinforced Al-based alloy matrix composites by infiltration casting process

Metallic amorphous phase reinforced metal matrix composites were fabricated by using infiltration casting process. Due to the high thermal stability of amorphous Ni-20.6Nb-40.2Ta (wt.%,,) and good castability of Al-6.5Si-0.25Mg (wt.%) alloy, sound composite specimens without casting defects were fabricated.
