Embodiment 1
[0039] Al 40 Fe 5 co 3 Cu 2 La 24 Ce 26 Preparation of Bulk Amorphous Composite Gold Materials
[0040] Step 1. Weighing various components and elements
[0041] According to alloy Al 40 Fe 5 co 3 Cu 2 La 24 Ce 26 The chemical composition and atomic percentage of each element are converted to calculate the mass fraction of each element, and they are precisely weighed on an electronic balance.
[0042] Step 2. Preparation of master alloy
[0043] Put the alloy raw material weighed in step 1 into the vacuum arc melting furnace, and evacuate to 5×10 -3 Pa, filled with argon protective gas, the argon pressure is 0.05 to 0.8 Mpa, the current is adjusted to 30-100 A, the alloy is smelted repeatedly for 4-6 times, and then Al is obtained by furnace cooling 40 Fe 5 co 3 Cu 2 La 24 Ce 26 master alloy.
