[0035] Further, a method for preparing a ternary Mg-Zn-Ce amorphous alloy comprises the following steps:
[0036] S1, by completing the atomic ratio in the glove box;
[0037] S2. Prepare the master alloy by melting the configured raw materials in a vacuum induction melting furnace;
[0038] S3. Obtain a small piece of appropriate size through mechanical grinding and cutting, ultrasonic cleaning, and alcohol cleaning;
[0039] S4. Put the small piece of metal into the quartz tube and put it into the belt throwing machine, evacuate to 0.005Pa, fill in nitrogen as a protective gas, ensure that the pressure difference between the upper end of the quartz tube and the cavity is 0.002Mpa, and the upper end of the upper end is 0.08MPa, Cavity 0.06Mpa;
[0040] S5. When the rotational speed of the copper roller reaches 3000r / min, turn on the power to melt the small pieces of metal, and finally obtain an amorphous strip with a width of 1-2mm and a thickness of 20-30μm.
