摘要：

A new alloy exhibiting high glass-forming ability was developed with the composition Fe70.7C6.7P10.4B5Si1.1Mn0.1Cr2MO2Ga2. This alloy exhibited excellent castability enabling net- shape-casting. The samples were prepared by copper-mould casting in conical rod form which has a small diameter of 3mm, a large diameter of 4mm, and a length of 54 mm, as well as in ring form with an outer diameter of 26 mm, an inner diameter of 18 nun and a thickness of I mm. The B-S and H-C values in DC conditions determined for the ring sample in the as-cast state are 0.45T and 1.7A/m, respectively, and for the ribbon in the as-cast state 0.5 T and 3.8 A/m, respectively. On the basis of the measured properties, large industrial use of this new alloy can be predicted.
