Embodiment 1

[0032] Manganese-based amorphous alloys are prepared according to the chemical expression shown in Table 1, and the preparation method is as follows:

[0033] (1) carry out batching according to each element atomic percentage proportioning of alloy composition, the required amount of elemental element B, Mn, Si in the batching process is Mn-B (the content of B is 3.35wt%) and Mn-Si (the content of Si is 3.35wt%) The content is 3.35wt%) to add as master alloy, supplemented with trace amounts of Mn, Si, B elemental substances as required;

[0034] (2) Use WK-IIA type non-consumable vacuum arc melting furnace for melting. In order to ensure the quality of the master alloy, the furnace body is evacuated before smelting to make the vacuum degree reach 3.0×10 -4 Pa, and then into high-purity argon (purity 99.99%). During smelting, reserve a smelting pot to hold titanium ingots, and smelt titanium ingots first to absorb the residual oxygen in the smelting furnace, and then use elec...

Abstract

The invention belongs to the technical field of amorphous alloys, and provides a manganese-based amorphous alloy and a preparation method and application thereof. The chemical general formula of the manganese-based amorphous alloy is MnxSiyBz, wherein 65<=x<=84, 6<=y<=25, 5<=z<=12, and x+y+z=100. The Mn-Si-B ternary system manganese-based amorphous alloy has excellent amorphous forming ability and thermal stability, and meanwhile keeps the maximum manganese content, the characteristic contribution of the manganese element to the manganese-based amorphous alloy can be fully exerted, and a material basis is provided for further research on the microcosmic nanostructure and potential abundant characteristics of the manganese-based amorphous alloy. In addition, the manganese-based amorphous alloy further has good flowability and oxidation resistance, preparation can be achieved through a rapid quenching melt-spinning method, the production efficiency of the manganese-based amorphous alloy is greatly improved, and then large-scale application of the manganese-based amorphous alloy is promoted. The manganese-based amorphous alloy is expected to be applied into catalytic materials or magnetic materials.

Description

technical field [0001] The application belongs to the technical field of amorphous alloys, and in particular relates to a manganese-based amorphous alloy and its preparation method and application. Background technique [0002] Amorphous alloy is a new type of metal material that lacks the periodic arrangement of atoms in crystalline materials, has a long-range disordered atomic structure, and has no grain boundary structure characteristics, and therefore exhibits excellent physical and chemical properties. Since its discovery, several amorphous alloy systems have been developed and have shown exceptional performance. [0003] Mn is a metal element with special structure and magnetic properties among the transition group metal elements. There are four allotropes in its solid state: α-Mn (complex body-centered cubic structure with 58 atoms in a single unit cell), β-Mn (complex body-centered cubic structure with 20 atoms in a single unit cell), γ-Mn (simple face-centered cub...
