Abstract

See full text

Boron-based amorphous alloys and a preparation method thereof is provided. The composition formula of the alloys is BaCobREcX1dX2eX3f, wherein RE is any one or more of La, Ce, Pr, Nd, Sm, Gd, Dy, Er and Y; X1 is any one or more of C, Si and Al; X2 is any one or two of Fe and Ni; X3 is any one or more of Zr, Nb, Mo, Hf, Ta and W; and a, b, c, d, e and f respectively represent atomic percent of each corresponding element in the formula, where: 45≤a≤55, 25≤b≤40, 10≤c≤20, 0≤d≤10, 45≤a+d≤55, 0≤e≤20, 25≤b+e≤40, 0≤f≤3, 10≤c+f≤20 and a+b+c+d+e+f=100. The preparation method of the boron-based amorphous alloy comprises: preparing master alloy ingots using an arc furnace or an induction melting furnace; and then obtaining amorphous ribbons with different thicknesses by a single copper roller melt-spinning equipment.
