Description

technical field [0001] The invention relates to a method for improving the plasticity of amorphous alloys by using supersonic particle bombardment technology, which belongs to the field of amorphous materials. Background technique [0002] Amorphous alloy is a new type of metal material. The unique long-range disordered and short-range ordered structure endows the material with excellent properties different from traditional metals, such as high yield strength, high elastic limit, etc.; in addition, amorphous alloy has good Corrosion resistance, excellent physical properties such as soft magnetic, hard magnetic and unique expansion characteristics. However, under tensile and compressive load tests, amorphous alloys will undergo shear failure along a major shear band, and there is almost no macroscopic plasticity. The low plastic deformation capacity severely limits the engineering application of amorphous alloys. [0003] In view of the poor plasticity of amorphous alloys, ...
