Abstract: A high strength Fe-based amorphous alloy composition excellent in amorphous forming ability is provided to extend more than 4mm of a maximum bulk amorphous diameter, and to increase productivity by precipitating Fe23B6 phase and Fe2Nb and restricting the precipitation of a-Fe and Fe2B. A high strength Fe-based amorphous alloy composition has excellent amorphous forming ability with common formulas FexByNbaY(66 atom%

Abstract translation: 提供非晶形成能力优异的高强度Fe基非晶态合金组合物以延伸大于4mm的最大块状无定形直径，并通过沉淀Fe23B6相和Fe2Nb并限制a-Fe和Fe2B的沉淀来提高生产率。 高强度Fe基非晶合金组合物具有优异的无定形形成能力，具有通式FexByNbaY（66原子％<= x <= 70原子％，21原子％<= y <= 25原子％，3原子％<= = 6原子％，3原子％<= b <= 5原子5）。 合金组成含有68原子％<= x <= 69原子％，22原子％<= y <23原子％3原子％<= a <= 5原子％4原子％<= b <= 5 原子％。
