Glass-Forming Ability of Fe60Co8Zr10Mo5W2B15 Alloy with Industrial-Pure Raw Materials

摘要：

Special remelting techincs including repeating the heating and quenching process for several times, electromagnetic mixing during the melting, increasing the superheating temperature, prolonging isothermal time can effectively decrease or remove the effect of impurity in raw materials on the glass-forming ability (GFA) of the alloy system. These technics were introduced to improve GFA of Fe60Co8Zr10MoSW2B15 alloys (△Tx = 64 K, Trg = 0.61, Trg= 0.59). Bulk metallic glasses of Fe60Co8Zr10Mo5W2B15 with the shape of rods (φ3×40) and plates (1×10×20) were casted into fully glassy state. It was proved the GFA of Fe60Co8Zr10MoSW2B15 with industrial raw materials is very close to that with high purity raw materials. Fe60Co8Zr10Mo5W2B 15 bulk metallic glass with industrial raw materials shows better potential appliance for their low cost.
