Description

technical field [0001] The invention relates to a method for joining dissimilar bulk amorphous alloys. Background technique [0002] Bulk amorphous alloy is an advanced metal material. The unique short-range order and long-range disordered liquid-like atomic structure arrangement characteristics endow it with excellent properties different from traditional crystalline metal materials, such as high strength and high corrosion resistance. Therefore, bulk amorphous alloys are considered to be a structural and functional material with excellent performance, and have broad application prospects in aerospace, aviation, sports, medical, military and other fields. [0003] However, the preparation of amorphous alloys usually requires sufficiently high cooling rates (>10 3 K / s) to suppress the crystallization phenomenon, and only by rapid solidification technology can the liquid structure be retained to obtain an amorphous structure, but this preparation method severely limits th...
