Problems solved by technology

However, the mechanical properties of the reclaimed amorphous alloy will decrease after remelting in this method, and this decline has an additive effect. After repeated recycling, the properties of the amorphous alloy will decrease Significant decline, so that the product performance requirements cannot be met

Embodiment 1

[0020] This example is used to illustrate the recycling method of the zirconium-based amorphous alloy waste provided by the present invention.

[0021] The general formula of the alloy composition is Zr by jaw mechanical crushing method. 63.5 Al 3.6 Cu 26 Ni 5.9 Y 1 The zirconium-based amorphous alloy die-casting handle recycled material is broken into block recycled materials with an average size of 3-5 cm, and 5 kg of the recycled material is weighed, and the rust removal, surface oxide removal and degreasing treatment are sequentially carried out. Then, an IRO-II oxygen content analyzer was used to detect the oxygen content of the zirconium-based amorphous alloy reclaimed material. As a result, the oxygen content was 1085ppm (ie 0.1085% by weight, ie A was 0.1085). Make the zirconium-based amorphous alloy reclaimed material and 19.15 grams of Y 2 o 3 (i.e. W2 =3.53A parts by weight) and 30.87 grams of Zr (ie W 1 =5.69A parts by weight) are mixed, and the gained mixtu...

Embodiment 2

[0029] This example is used to illustrate the recycling method of the zirconium-based amorphous alloy waste provided by the present invention.

[0030] The general formula of the alloy composition is Zr by jaw mechanical crushing method. 62.4 Ti 11.2 Cu1 3.3 Ni 9.8 be 3.3 The zirconium-based amorphous alloy die-casting handle recycled material is broken into block recycled materials with an average size of 3-5 cm, and 5 kg of the recycled material is weighed, and the rust removal, surface oxide removal and degreasing treatment are sequentially carried out. Then, an IRO-II oxygen content analyzer was used to detect the oxygen content of the zirconium-based amorphous alloy reclaimed material. As a result, the oxygen content was 2103ppm (ie 0.2103% by weight, ie A was 0.2103). Make the zirconium-based amorphous alloy reclaimed material and 37.12 grams of Y 2 o 3 (i.e. W 2 =3.53A parts by weight) and 59.83 grams of Zr (ie W 1 =5.69A parts by weight) are mixed, and the gain...

Embodiment 3

[0038] This example is used to illustrate the recycling method of the zirconium-based amorphous alloy waste provided by the present invention.

[0039] Adopt the zirconium-based amorphous alloy recovery material in embodiment 2 (oxygen content is 2103ppm, and A is 0.2103), and make the described zirconium-based amorphous alloy of 5 kilograms and the Y of 31.86 grams 2 o 3 (i.e. W 2 =3.03A parts by weight) and 72.45 grams of Zr (ie W 1 =6.89A parts by weight) are mixed, and the gained mixture is added to the vacuum melting chamber of the intermediate frequency vacuum induction melting furnace (produced by Jinzhou Sante Vacuum Metallurgical Technology Industry Co., Ltd., model ZG-03) with rated capacity of 25 kilograms, Vacuum the furnace body, fill it with argon, wash the furnace with argon, and control the absolute vacuum degree of the vacuum smelting chamber to be 0.08Pa, so that the resulting mixture is smelted at a power of 25kW until it is completely melted. 300° C. abo...

Abstract

The invention provides a method for recycling zirconium-based amorphous alloy waste, which comprises the steps of mixing the zirconium-based amorphous alloy waste with an additive, fusing the mixture under vacuum, filtering fusant, pouring and cooling in the presence of a protective gas, wherein the additive is the mixture of Zr and Y2O3. When the zirconium-based amorphous alloy waste is treated by the method for recycling zirconium-based amorphous alloy waste provided by the invention, the oxygen content and bending strength of the obtained zirconium-based amorphous alloy are very close to those of the conventional zirconium-based amorphous alloy, and the impact toughness of the obtained zirconium-based amorphous alloy is even higher than the conventional zirconium-based amorphous alloy.

Description

technical field [0001] The invention relates to a recycling method of zirconium-based amorphous alloy waste. Background technique [0002] Amorphous metal materials have excellent properties such as high strength and hardness, wear resistance, corrosion resistance, greater elasticity and high electrical resistance, and also exhibit excellent superconductivity and low magnetic loss. And other characteristics, so amorphous metal materials are considered to be the most potential new structural materials, which are widely used in machinery, IT electronics, military industry and other fields. The emergence of bulk amorphous metal materials has greatly promoted the research and application of non-gold metal materials. [0003] In actual production, the performance of bulk amorphous alloys is very sensitive to the purity of raw materials, impurity elements, and ambient atmosphere. Especially, amorphous alloys will inevitably introduce a small amount of impurities such as oxygen du...
