Fabrication of bulk metallic glasses in the alloy system Fe–C–Si–B–P–Cr–Mo–Al using hot metal and industrial ferro-alloys

Abstract

Fe-base bulk metallic glasses in the alloy system Fe–C–Si–B–P–Cr–Mo–Al have been developed using hot metal and industrial ferro-alloys. The amorphous alloys can be cast into fully amorphous rods with diameters of up to 4 mm, demonstrating high glass-forming ability and high strength (>3 GPa). Thermal stability and crystallization behavior of the Fe–C–Si–B–P–Cr–Mo–Al bulk metallic glasses are also investigated. The Fe-base bulk metallic glasses can be produced cost-effectively and massively for extensive structural applications.
