Embodiment 1
[0039] Preparation of Ti 41 Zr 25 be 32 Fe 2 bulk amorphous alloy;
[0040] In the first step, the atomic percent composition of the Ti-based bulk amorphous alloy is converted into mass percent, and the raw materials are weighed out.
[0041] The raw materials are titanium rods (purity: 99.4%), zirconium rods (purity: 99.7%), beryllium blocks (purity: 99.99%) and iron blocks (purity: 99.99%). The above materials are polished and scaled and then ultrasonically cleaned with acetone or alcohol. , the atomic percent composition of the Ti-based bulk amorphous alloy is converted into mass percent, and the alloy raw materials are prepared by weighing according to the mass percent, and the weighing tool is a balance with an accuracy of 0.0001 g.
[0042] In the second step, the raw materials are mixed and put into an electric arc furnace or an induction melting furnace to melt under vacuum or gas protection conditions and make a master alloy ingot.
