Embodiment 1
[0081] (1) Preparation of Zr 58 Cu 12 Ni 12 al 15 Nb 3 Amorphous alloy: Zr, Cu, Ni, Al, Nb with purity ≥ 99.99%, 5 kinds of metals are mixed according to the atomic percentage of 58:12:12:15:3, arc melting in a high-purity argon atmosphere, first The Zr-Nb binary alloy is melted, then mixed with other metal elements to melt the master alloy ingot, and then the alloy ingot is melted and poured into a copper mold. The size of the copper mold is Φ5mm*50mm, and the Zr-based amorphous alloy sample is prepared.
[0082] (2) Process the sample into a cylindrical sample 7 of Φ3mm*3mm, use 400#-2000# sandpaper to grind the upper and lower bottom surfaces of the cylindrical sample from small to large, so that the flatness of the two end faces of sample 7 is better than 5 μm, and then Rinse and dry with absolute ethanol.
[0083] (3) The sample 7 is placed between the incident rod 4 and the transmission rod 9, and a stop ring 6 made of 18Ni300 maraging steel with an outer diameter o...

[0088] (1) Preparation of Zr 63 Cu 12 Ni 12 al 10 Nb 3 Amorphous alloy: Zr, Cu, Ni, Al, Nb with a purity ≥ 99.99%, 5 kinds of metals are mixed according to the atomic percentage 63:12:12:10:3, arc melting in a high-purity argon atmosphere, first The Zr-Nb binary alloy is melted, then mixed with other metal elements to melt the master alloy ingot, and then the alloy ingot is melted and poured into a copper mold. The size of the copper mold is Φ5mm*50mm, and the Zr-based amorphous alloy sample is prepared.
[0089] (2) Process the sample into a cylindrical sample 7 of Φ3mm*3mm, use 400#-2000# sandpaper to grind the upper and lower bottom surfaces of the cylindrical sample from small to large, so that the flatness of the two end faces of sample 7 is better than 5 μm, and then Rinse and dry with absolute ethanol.
[0090] (3) The sample 7 is placed between the incident rod 4 and the transmission rod 9, and a stop ring 6 made of 18Ni300 maraging steel with an outer diameter of...
