Embodiment
[0029] The formula of the amorphous alloy in the present invention is proportioned according to the ingredients in the following table, and the number after the element symbol is the mole percentage of each element.
[0030]
[0031]
[0032] Alloy preparation method:
[0033] Step 1: Mix the amorphous alloy raw materials with purity greater than 99.99% according to the formula, stir and mix them evenly;
[0034] Step 2: Melt the mixed raw materials in a vacuum or argon atmosphere by arc melting or other conventional melting methods, and the melting is repeated 3 times; the vacuum degree of the melting process is 10 -3 Pa, or the pressure of argon atmosphere is 0.01MPa, the amorphous alloy ingot is obtained after cooling; the melting temperature is 140℃ higher than the melting point of the amorphous alloy in the formula; the cooling rate of the amorphous ingot after melting is 6×10 3 K / s;
[0035] Step 3: After crushing the amorphous alloy ingot obtained in step 2, it is smelted again ...
