Description

technical field [0001] The invention relates to an amorphous alloy, in particular to a zirconium-based amorphous alloy. Background technique [0002] Amorphous alloys prepared by rapid solidification of alloys from gaseous or liquid states do not have long-range atomic order, but have a special amorphous structure, so that amorphous alloys have incomparable mechanical properties that crystalline alloys cannot match. , such as high strength, high hardness, high elasticity, high fracture toughness and corrosion resistance, wear resistance, have great potential application prospects in aerospace, aviation and biomedical fields. Zr-based amorphous alloys have been successfully used to prepare golf club heads, tennis rackets, solar wind collectors for aerospace and other products due to their high amorphous forming ability and excellent performance. Typical systems have Zr-Ti-Ni-Cu-Be (A.Pekerand W.L.Johnson, Appl.Phys.Lett.63, 2342 (1993).), Zr-Al-Ni-Cu-RE (J.Luo, H.P. Duan, C...
