Description

Technical field [0001] The invention relates to the field of metal alloys, in particular to a zirconium-based amorphous alloy. Background technique [0002] Since the atomic arrangement of amorphous alloys does not have the characteristics of long-range order, there are no dislocations in the structure, and no grain boundaries. Therefore, compared with ordinary polycrystalline metal materials, amorphous alloys have high strength, corrosion resistance and wear resistance. With excellent performance, it can be used as raw materials for the preparation of microelectronic devices, sporting goods, high-end luxury goods, and consumer electronics. The usual method for preparing amorphous alloys is to rapidly cool the alloy melt to the glass transition temperature (T g ) Below, because the cooling rate is too fast, the nucleation and growth of the crystal are avoided, and finally a completely amorphous structure is obtained. The slower the cooling rate required for the material to form ...
