Embodiment Construction

[0032] 1. Embodiment of the present invention

[0033] The preparation method of the zirconium-based amorphous alloy product of the present invention is as follows: the amorphous raw materials are smelted under vacuum conditions or in an argon atmosphere according to the proportion, and the vacuum degree is 10 -1 -10 -2 Any pressure within the Pa range is acceptable. If the argon atmosphere is selected, the argon pressure can be adjusted within the range of 0.01-0.1 MPa, preferably 0.05-0.08 MPa. As long as the vacuum degree or argon pressure is within the range, the melting effect can be guaranteed. Cooldown rate is set to 10 2 -10 3 K / s can be used without any significant effect. The raw materials of Zr and Hf are selected from zircon raw ore dressing and smelting without removing Hf. The common purity of Zr and Hf in this product can reach more than 99.9%; the purity of Al, Cu, Ni, Y and Ag metal raw materials is selected as More than 99.9%.

Abstract

The invention discloses zircon-based amorphous alloy. The zircon-based amorphous alloy is composed of Zr, Hf, Al, Cu, Ni, Y and Ag elements. The zircon-based amorphous alloy is composed of, by atomic molar percentage, 40-70% of Zr, 1-10% of Hf, 15-40% of Al, 5-15% of Cu, 5-15% of Ni, 0.2-5% of Y and 0.2-5% of Ag. The zircon-based amorphous alloy is good in glass forming ability (GFA) and good in glass forming capacity, the zircon-based amorphous alloy is a specular surface after being formed and does not need to be additionally machined, and the cost is low.

Description

technical field [0001] The invention relates to an amorphous alloy material, in particular to a zirconium-based amorphous alloy material and a preparation method thereof. Background technique [0002] Compared with traditional metal materials, amorphous alloys have many excellent properties such as high hardness, high strength, high corrosion resistance and large elastic limit. Due to its excellent properties, amorphous alloys have great application prospects in high-end electronic products, medical device products and the automotive industry, and have become a new material with great development prospects. So far, more than ten kinds of amorphous alloys such as Zr-based, Pd-based, Fe-based, Ti-based, Mg-based, Li-based, and Co-based have been developed through various reasonable alloy designs and conventional casting methods. [0003] Zr-based amorphous alloy is an important part in the history of amorphous alloy development, and it is also one of the important systems tha...
