Abstract

The invention provides a zirconium-based amorphous alloy. The components of the amorphous alloy adopt ZraREbTMcBed, wherein, a is larger than or equal to 30 and less than and equal to 45, b is larger than or equal to 15 and less than and equal to 25, c is larger than or equal to 15 and less than and equal to 30, d is larger than or equal to 19 and less than and equal to 25, a, b, c and d are mol percentages, and a plus b, c and d is equal to 100; RE is selected from one or more of the rare earth metals; and TM is selected from one or more metal(s) of the IB group metals, the, IIB group metals, the IVB group metals, the VB group metals, the VIIB group metals and the VIII group metals. The invention has the advantages that the liquefaction temperature (Tl) of the amorphous alloy is greatly reduced, the high temperature resistance requirements of casing devices during the amorphous alloy casting process are greatly reduced, and the production cost is also greatly reduced. In addition, the hardness, the impact toughness and the anti-bending strength of the amorphous alloy can also meet the requirements, and when the liquefaction temperature (Tl) of the amorphous alloy is greatly reduced, other properties of the amorphous alloy can also meet the requirements.

Description

technical field [0001] The invention relates to an amorphous alloy and a preparation method thereof, more specifically to a zirconium-based amorphous alloy and a preparation method thereof. Background technique [0002] Zirconium-based amorphous alloys have extremely high strength, hardness, wear resistance, corrosion resistance and high electrical resistance, and also exhibit excellent superconductivity and low magnetic loss. They are widely used in IT electronics, machinery, chemical industries and other industries. It has broad application prospects. [0003] For example, US5288344A1 discloses a zirconium-based amorphous alloy, the composition of which is: (Zr 1-x Ti x ) a1 ETM a2 (Cu 1-y Ni y ) b1 LTM b2 be c , where, x and y are atomic fractions, a1, a2, b1, b2 and c are atomic percentages, wherein ETM is at least one early transition metal selected from the group consisting of V, Nb, Hf and Cr, wherein The atomic percentage of Cr is not higher than 0.2a1; LTM...
