开发了一种具有高非晶形成能力的新型合金，其成分为Fe 70.7C6.7P10.4B5Si 1.1Mn 0.1Cr2Mo2Ga 2。该合金表现出优异的可铸性，使得能够进行净形铸造。样品通过铜模铸造制备成具有3 mm的小直径、4 mm的大直径和54 mm的长度的锥形棒形式以及具有26 mm的外径的环形形式，内径为18 mm，厚度为1 mm。铸态下的电流密度分别为0.45T和1.7A/m，铸态下的电流密度分别为0.5T和3.8A/m。根据测量的性能，可以预测这种新合金的大规模工业应用。
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.
