Embodiment 1
[0030] Example 1, Tb 56 co 20 al 24 Preparation of Bulk Amorphous Alloy
[0031] Use Tb, Co and Al with a purity of more than 99.9% and a molar ratio of 56:20:24 to prepare a terbium-based bulk amorphous alloy. Melt in the furnace, mix evenly, and obtain the master alloy ingot of Tb-Co-Al ternary alloy after cooling; then use the conventional metal mold casting method to remelt the ingot, and use the suction casting device in the electric arc furnace to The master alloy melt is sucked into the water-cooled copper mold, and the composition is Tb 56 co 20 al 24 The bulk amorphous alloy, whose morphology is as follows figure 1 As shown, the diameter is 3mm.
[0032] Such as figure 2 X-ray diffraction (XRD) shown demonstrates that the alloy is nearly completely amorphous. Such as image 3 The thermal analysis (DSC) diagram shown, its glass transition temperature (T g ), crystallization onset temperature (T x ), the width of the subcooling interval (ΔT=T x -T g ) are...
