[0002] Bulk amorphous alloy refers to an amorphous alloy material that reaches the millimeter level on a three-dimensional scale; in 1934, German physicist Kramer obtained an amorphous film by vapor deposition. Excellent mechanical properties, physical and chemical properties, wear resistance and corrosion resistance and good processing performance; nickel-based amorphous alloys also have high magnetic permeability and low-loss soft magnetic properties, nickel-based amorphous alloys are widely used in industrial fields; At present, most amorphous alloys are in the form of thin films, filaments, strips and powders, which greatly limits the application of amorphous alloys. Therefore, it is urgent to explore new methods for preparing bulk amorphous alloys.
