preparation example Construction

[0047] The present invention also provides a method for preparing the U-based amorphous alloy described in the above technical solution, comprising the following steps:

[0048] According to the ratio of each metal element in the U-based amorphous alloy, U, Al and Group VIII metals are mixed and arc smelted to obtain a uranium alloy master ingot;

[0049] After induction heating and melting the uranium alloy master ingot, the obtained alloy melt is stripped to obtain the U-based amorphous alloy.

[0050] In the present invention, unless otherwise specified, all preparation materials are commercially available products well known to those skilled in the art.

[0051] According to the ratio of each metal element in the U-based amorphous alloy, the invention mixes U, Al and group VIII metals, and performs electric arc melting to obtain a uranium alloy mother ingot.

[0052] In the present invention, the purity of U is preferably ≥ 99.5 wt%, and the purity of Al or Group VIII met...

Abstract

The invention relates to the technical field of nuclear material amorphous alloys, and particularly relates to a U-based amorphous alloy and a preparation method and application thereof. The U-based amorphous alloy comprises, by atomic percent, 55-65% of U, 5-15% of Al and the balance VIII-family metal elements. The VIII-family metal elements comprise Fe or Co. The U-based amorphous alloy has very high amorphous forming capacity and higher heat stability.

Description

technical field [0001] The invention relates to the technical field of nuclear material amorphous alloys, in particular to a U-based amorphous alloy and a preparation method and application thereof. Background technique [0002] Uranium alloys have been reported as early as the 1950s. At that time, Bleiberg et al. reported in Volume 212 of the journal Transactions of the American Institute of Mining and Metallurgical Engineers that U-Si amorphous crystals were first obtained by irradiation. In the 1980s, the research on this amorphous alloy reached its climax, and the representative work was published by Giessen et al. in the journal "Acta Metallurgica" Volume 30 and "Proceedings of the 3rd international Conference on Rapid Quenching" International Conference U-M (M=Fe, Mn, Co, Ni, Cr, V, Si, Os, Ir, Pd) series of binary amorphous alloys, and Drehman et al. systematically in the journal "Journal of Non-Crystalline Solids" Volume 76 U-Fe, U-Ni and U-Co amorphous alloys are s...
