[0029] Example 1: Preparation of Nb 0.42 Ni 0.39 Co 0.15 Zr 0.04 Amorphous alloy

[0030] First, the raw materials with a purity of ≥99.9% are distributed according to the chemical composition ratio Nb 0.42 Ni a Co b Zr c M d Dosing is performed where a, b, c, d are atomic percent of each component, and a=0.39, b=0.15, c=0.04, d=0. Then it is repeatedly smelted in a vacuum arc furnace to obtain a master alloy with uniform composition. Better than 3×10 in vacuum -2 Under Pa vacuum conditions, the master alloy is placed in an induction furnace of a rapid solidification device to be melted to obtain a master alloy melt. The master alloy melt is sprayed onto the surface of the high-speed rotating copper roller, the surface linear velocity of the roller is about 20~40m / s, and the chemical composition of Nb is obtained by cooling. 0.42 Ni 0.39 Co 0.15 Zr 0.04 The Nb-based amorphous alloy strips were tested for their thermodynamic stability and hydrogen permeation proper
