Description
Technical Field
The invention relates to the field of metal materials, in particular to a Fe-Mo-B-Nb-Y bulk amorphous alloy with high glass forming capability, and a preparation method and application thereof.
Background
In recent years, iron-based amorphous alloys have attracted increasing attention from researchers due to their high strength, extremely strong corrosion resistance and good soft magnetic properties. Iron-based alloys have low amorphous forming ability and require a high cooling rate during cooling, so that the resulting samples are all in the form of filaments or ribbons. As a soft magnetic material, iron-based amorphous alloy strips have been applied in the field of magnetic materials. However, in practical application, the iron-based amorphous alloy ribbon reduces the saturation magnetization due to the existence of gaps between the ribbons, thereby reducing the efficiency of the transformer. In addition, due to the influence of the size, the iron-based amorphous alloy is difficult to prepare a magnetic device with a complex shape, and thus the application of the iron-based amorphous alloy is greatly limited, so that the iron-based bulk amorphous alloy with a large glass forming capability is urgently required to be searched.
Compared with La-based, zr-based, pd-based and Mg-based bulk amorphous alloys, the preparation of iron-based bulk amorphous alloys is more difficult. In 1995, the Inoue research group of Japan was first prepared successively and successfully a series of iron-based bulk amorphous alloys, such as Fe- (Al, ga) -P-C-B, fe- (Zr, hf, nb) - (Cr, mo, W) -B, fe-Co-Ln-B, fe-Co-Ni-Si-B, fe-Si-B-Zr, etc., using high purity metals and non-metals as raw materials by casting with a copper mold. Wherein the maximum diameter of the Fe-Co- (Zr, nb, ta) - (Mo, W) -B rod-like sample is 6mm. At present, the report of improving the glass forming capability of an amorphous alloy by mixing rare earth elements and large-size elements is less, and a large exploration space still exists.

(2) Placing the alloy ingot into a crucible of a pouring system, vacuumizing a furnace chamber, introducing high-purity argon with the purity of 99.95-99.99wt% to 350-400mbar, completely melting the alloy ingot, pouring the alloy ingot into a mold, and cooling and forming.
Preferably, in step (1), the purity of the elemental metal raw material is not less than 99.9%.
Preferably, in the steps (1) and (2), the vacuum is applied to 3.5X10 -3 -5×10 -3 Pa。

Preferably, in step (2), the alloy ingot is melted at 200-300A, and then the alloy ingot is completely melted at 400-500A.
In order to solve the above technical problems, a third object of the present invention is to provide an application of a bulk amorphous alloy of Fe-Mo-B-Nb-Y with high glass forming ability in the field of magnetic materials, such as transformers, sensors, etc.

The method controls the proper content of the Y element in the amorphous alloy, and if the value of x is too large or too small, the glass forming capacity of the amorphous alloy can be changed, so that an amorphous structure is not easy to form. In addition, when the radius of the amorphous alloy is greater than the size range of 3mm, it cannot be formed into a completely amorphous structure.

As shown in Table 1, the saturation magnetization of the samples in examples 1 to 3 was singly changed with the increase of the Y content, showing a decreasing trend of change. Referring to FIG. 4, ΔT x As can be seen from the change curve of x, the as-cast alloy of the embodiment of the invention has a wider supercooled liquid region, so that the as-cast alloy has higher thermal stability and glass forming capability. As shown in fig. 5, the magnetization of the amorphous alloy of the example increases sharply with the increase of the magnetic field and then reaches saturation gradually under the low magnetic field, which indicates that the alloy exhibits typical soft magnetic properties, and fig. 6 shows the hysteresis loop of the comparative example, and the examples and the comparative examples have soft magnetic properties as can be seen from the change rule of the hysteresis loops of fig. 5 to 6.
