[0019] Example 1
[0020] The composition (atomic percentage) of the FeZrYB bulk amorphous alloy of this embodiment is: Fe 73%, Zr 2%, Y 4%, and B 21%. The preparation process and steps are as follows: The industrial pure metal raw materials Fe, Zr, Y, and FeB alloy are prepared according to the FeZrYB bulk amorphous alloy composition of this embodiment, and then used in a vacuum non-consumable electric arc furnace under argon protection For smelting, the smelting current density is 150A / cm 2 , The alloy is repeatedly smelted 4 times; a copper mold is used for negative pressure suction casting to obtain a bulk amorphous alloy with a size of 1mm×10mm×80mm. The magnetic properties of the FeZrYB bulk amorphous alloy prepared in this embodiment were measured at room temperature, as shown in FIG. 1. It can be seen from the drawings that the FeZrYB bulk amorphous alloy of the present invention has very excellent magnetic properties, and the saturation magnetization is M s = 1.1T.
