Embodiment 1

[0030] This embodiment relates to an Al 87 Ni 8 Ce 5 Alloys and methods of making them.

[0031] Using commercially available high-purity Al, Ni, and Ce block metals as raw materials, first clean the surface of the high-purity metal block, and weigh the corresponding metal block according to the molar percentage content of Al 87%, Ni 8%, and Ce 5%. , and then under an argon protective atmosphere (atmospheric pressure of 1.1 standard atmosphere), the three metal blocks of Al, Ni and Ce were smelted into master alloy ingots by arc melting method. In order to make the composition of master alloy ingots uniform, each group of samples was melted 6 times. Then cut about 2g of the alloy from the master alloy ingot, and remove the surface oxide film, and then melt it by arc melting under the protective atmosphere of argon (atmospheric pressure of 1.1 standard atmosphere), and quickly cast it by vacuum casting method. The alloy melt is suction-cast into a wedge-shaped copper mold t...

[0033] This embodiment relates to an Al 85.5 Ni 9.5 Ce5 Alloys and methods of making them.

[0034] Using commercially available high-purity Al, Ni, and Ce block metals as raw materials, first clean the surface of the high-purity metal block, and weigh the corresponding metal block according to the molar percentage content of Al 85.5%, Ni 9.5%, and Ce 5%. , and then under an argon protective atmosphere (atmospheric pressure of 1.15 standard atmospheres), the three metal blocks of Al, Ni and Ce were smelted into master alloy ingots by arc melting method. In order to make the composition of master alloy ingots uniform, each group of samples was melted 6 times. Then cut about 2g of the alloy from the master alloy ingot, and remove the surface oxide film, and then melt it by arc melting under the protective atmosphere of argon (atmospheric pressure of 1.15 standard atmosphere), and quickly cast it by vacuum suction casting The alloy melt is suction-cast into a wedge-shaped copp...

Abstract

The invention relates to Al - Ni - Ce system Al-based amorphous alloy and a preparation method thereof. The alloy comprises components in the following molar percentage content: 85-87% of Al, 8-10% of Ni and 5-7% of Ce. The invention also relates to the preparation method of the Al-Ni-Ce system Al-based amorphous alloy. Compared with the existing Al-based amorphous alloy, the alloy provided by the invention is prepared by a wedge mold vacuum suction casting method by using aluminum as a main component, and nickel and cerium as alloy elements, and has the advantage of strong amorphous forming ability, which enables the alloy to have a broad application prospect in the field of novel lightweight structural material.

Description

technical field [0001] The invention relates to an amorphous alloy and a preparation method thereof, in particular to an Al-Ni-Ce series aluminum-based amorphous alloy and a preparation method thereof. Background technique [0002] Since P.O.L.Duwez et al published Au-Si amorphous Since the alloys, the preparation and properties of amorphous alloys have become one of the focus of people's research. In 1988, Y.He (Y.He, S.J.Poon and G.J.Shiflet, Synthesis and Properties of Metallic Glasses that Contain Aluminum, Science, 1988, Vol.241, 1640-1642) and A.Inoue (A.Inoue, K .Ohtera,A.-P.Tsai and T.Masumoto,Aluminum-Based Amorphous Alloys with Tensile Strength above 980MPa(100kg / mm 2 ), Japanese Journal of Applied Physics, 1988, Vol.27, pL479-L482) and others developed an aluminum-based amorphous alloy with an aluminum content of more than 80% (mol fraction), high strength, and good toughness, and because the aluminum-based amorphous alloy Crystalline alloys have a series of ad...
