Embodiment 1
[0026] Step 1: Preparation of Cu 43 Zr 43 Zn 14 For a sample of 5g, weigh 1.8047g of pure Cu and 2.5907g of pure Zr, and put them in a well-polished water-cooled crucible;
[0027] Step 2: Evacuate the electric arc furnace to a vacuum of 5×10 -5 Pa, and then backfill Ar gas with a purity of 99.999% to one atmospheric pressure;
[0028] Step 3: Turn on the electric arc furnace and heat up to the melting point of the alloy prepared in step 1, turn the alloy ingot over, re-melt, repeat 3 times to mix the alloy evenly to obtain Cu 50 Zr 50 master alloy;
[0029] Step 4: Remove the surface scale of the master alloy and crush it, weigh 0.6046g of pure Zn, and mix it;
[0030] Step 5: Put it into the quartz test tube in the high-vacuum high-frequency induction melting-blow casting furnace;
[0031] Step 6: Evacuate the high-vacuum high-frequency induction melting-blow casting furnace to a vacuum of 5×10 -5 Pa, and then backfill Ar gas with a purity of 99.999% to one atmospher...

[0035] Step 1: Preparation of Cu 43 Zr 43 Zn 14 For a sample of 5g, weigh 1.8047g of pure Cu and 2.5907g of pure Zr, and put them in a well-polished water-cooled crucible;
[0036] Step 2: Evacuate the electric arc furnace to a vacuum of 5×10 -5 Pa, and then backfill Ar gas with a purity of 99.999% to one atmospheric pressure;
[0037] Step 3: Turn on the electric arc furnace and heat up to the melting point of the alloy prepared in step 1, turn the alloy ingot over, re-melt, repeat 4 times to mix the alloy evenly to obtain Cu 50 Zr 50 master alloy;
[0038] Step 4: Remove the surface scale of the master alloy and crush it, weigh 0.6046g of pure Zn, and mix it;
[0039] Step 5: Put it into the quartz test tube in the high-vacuum high-frequency induction melting-blow casting furnace;
[0040] Step 6: Evacuate the high-vacuum high-frequency induction melting-blow casting furnace to a vacuum of 5×10 -5 Pa, and then backfill Ar gas with a purity of 99.999% to one atmospher...
