Description

[0001] The present invention belongs to the technical field of amorphous alloys, and particularly relates to a preparation method of an amorphous alloy and an amorphous alloy. Background Art

[0002] Amorphous alloy is a new generation of high-performance metal material different from traditional metals. Due to its unique disordered atomic structure, it combines the excellent properties of metals and glasses, solids and liquids, and thus has a wide range of applications in various fields.

[0003] However, the application and popularization of amorphous alloys are restricted by their preparation processes and equipment. During the popularization process of amorphous alloys in the form of bulk, strips, and powders in the market, amorphous alloy strips are the most widely used among the three due to their excellent properties and the advantages of being easier to process and utilize.

[0004] However, due to factors such as the large technical difficulty of the preparation process, the limitations of the processing technology, and the high production equipment cost of amorphous alloy powders and bulk materials, their degree of popularization is far less than that of amorphous alloys in strip form. In fact, powders and bulk materials do not need to go through the rolling process during preparation, and their internal structures are relatively uniform. Therefore, they have higher strength and toughness than strips. At the same time, powders and bulk materials are more adaptable when facing some specific field requirements. Summary of the Invention

The terms "first" and "second" are only used for the purpose of convenient description and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of technical features. The meaning of "a plurality" is two or more unless otherwise specifically defined.

[0031] Please refer to Figure 1 and Figure 2, embodiments of the present application provide a method for preparing an amorphous alloy, and an amorphous alloy 34 prepared by this method. It can be understood that the amorphous alloy 34 can be an iron-based amorphous alloy 34, an aluminum-based amorphous alloy 34 or a titanium-based amorphous alloy 34, which can be selected according to actual situations and are not limited here. The amorphous alloy 34 in the present application is a zirconium-based amorphous alloy 34, where the molecular formula of the zirconium-based amorphous alloy 34 is Zr 35 Ti 30 Cu 8.25 Be 26.75 (at%).

[0032] Please refer to Figures 1 to 3 , the method for preparing the amorphous alloy includes the following steps:

[0033] S1: Heating. Prepare a melting furnace 10 with a heating chamber. The melting furnace 10 is provided with a liquid outlet hole communicating with the heating chamber. Put the amorphous alloy raw material into the heating chamber, close the liquid outlet hole and heat the amorphous alloy raw material to the molten state; the melting furnace 10 can heat by means of resistance heating or gas heating, so as to raise the temperature of the amorphous alloy raw material located in the heating chamber. For example, raise the temperature to above 1000 degrees Celsius, which is higher than the melting point of the amorphous alloy raw material, so that the amorphous alloy raw material is in a liquid state. The amorphous alloy 34 has a supercooled liquid region, that is, when the temperature rises to near the glass transition temperature (T g ) of the amorphous alloy 34, the amorphous alloy 34 is in the supercooled liquid region and can remain in a liquid state. In this region, the amorphous alloy 34 exhibits a relatively high viscosity and unique rheological behavior.

[0034] Please refer to Figures 1 to 3 , it can be understood that a slidable cover plate can be provided at the liquid outlet hole. During the heating step, the cover plate slides to the liquid outlet hole and seals the liquid outlet hole, so that the molten amorphous alloy raw material does not flow out of the heating chamber.

[0035] S2: Cutting. Open the liquid outlet hole, that is, by sliding the cover plate in the reverse direction so that it covers at most part of the liquid outlet hole. The amorphous alloy raw material flows out of the heating chamber in a liquid column 31. Cut the liquid column 31 multiple times to obtain a plurality of small-sized metal liquid columns 32, that is, perform intermittent cutting on the liquid column 31. In each cutting process, cut off the lowermost part of the liquid column 31 and form a metal liquid column 32. The metal liquid column 32 is separated from the liquid column 31 and falls downward under the action of gravity.

[0036] S3: Cooling. Cool the metal liquid column 32 to obtain the amorphous alloy 34. Each metal liquid column 32 can be cooled to room temperature by a cooling device to obtain the required amorphous alloy 34.

[0037] The preparation method of the amorphous alloy according to the embodiment of the present application is to heat the amorphous alloy raw material to a molten state, then open the liquid outlet hole provided on the melting furnace 10, so that the molten amorphous alloy raw material flows out from the liquid outlet hole, and then cut the liquid column 31 at the liquid outlet hole, continuously cutting it into a plurality of metal liquid columns 32, and then cooling the metal liquid columns 32, thereby realizing the effective preparation of the amorphous alloy 34. The process is simple and the preparation cost of the amorphous alloy 34 is low.

[0038] Optionally, in the cooling step, the cooling rate range can be 10 3 ~10 7 K / s, so that the metal liquid column 32 can be rapidly cooled to obtain the amorphous alloy 34.

[0039] Please refer to Figures 1 to 3 , it can be understood that the metal liquid column 32 can be in the form of powder, sphere, strip, snowflake or block, and thus the obtained amorphous alloy 34 can also be in the form of powder, sphere, strip, snowflake or block. During the cutting of the liquid column 31, the liquid column 31 continuously extends and flows out from the liquid outlet hole at the same time, so that the cutting process can continue until all the molten amorphous alloy raw material in the heating cavity flows out.

[0040] Optionally, before the liquid amorphous alloy raw material flows out of the heating cavity, the molten amorphous alloy raw material can be stirred by a stirring mechanism to make it evenly mixed, which is convenient for subsequent flowing out from the liquid outlet hole.

[0041] In some embodiments, the preparation method of the amorphous alloy further includes pressurization. In the pressurization step, gas is filled into the heating cavity to drive the molten amorphous alloy raw material to flow out from the liquid outlet hole.

[0042] Optionally, the heating cavity can be sealed by a furnace cover, and then gas is filled into the heating cavity to increase the air pressure in the heating cavity, so that the amorphous alloy raw material flows out of the heating cavity from the liquid outlet hole.

[0043] It can be understood that the opening degree of the liquid outlet hole can be adjusted through the cover plate, and combined with the flow rate of the gas filled into the heating cavity, that is, the air pressure in the heating cavity is adjusted, so that the shape of the liquid column 31 at the liquid outlet hole and the flowing rate of the liquid column 31 can be controlled. As the amorphous alloy raw material flows out of the heating cavity, gas is continuously supplemented into the heating cavity at the same time, so that the air pressure in the heating cavity remains stable, and the flowing liquid column 31 is uniform and the shape is stable.

[0044] Optionally, the air pressure range in the heating cavity is 0.1 Mpa to 20 Mpa, and the gas inflow rate into the heating cavity is in the range of 1000 to 6000 ml / min.

[0045] In some embodiments, the gas is an inert gas.

[0046] Optionally, the inert gas can be nitrogen or argon to increase the outflow pressure of the molten amorphous alloy raw material, ensure the stable outflow of the liquid column 31, and the inert gas can keep the amorphous alloy raw material in the heating cavity in an oxygen-free environment, avoiding the oxidation of the molten amorphous alloy raw material in the heating cavity.

[0047] Please refer to Figures 1 to 3 , in some embodiments, in the cutting step, a spray gun 30 is used to spray gas and / or liquid to cut the liquid column 31.

[0048] Please refer to Figures 1 to 3 , optionally, the nozzle of the spray gun 30 sprays high-pressure gas towards the liquid column 31 to cut the liquid column 31, obtaining a metal liquid column 32. At the same time, the ejected high-pressure gas can also pre-cool the cut metal liquid column 32, preventing the atoms from arranging into an ordered crystal structure and keeping their disordered atomic structure arrangement to form an amorphous state, initially ensuring the shape of the metal liquid column 32. The gas can be nitrogen or argon. Adjust the supply speed, supply amount, and spraying angle of the gas to control the cutting accuracy and the size and shape of the final metal liquid column 32, so that the metal liquid column 32 can be in the form of powder, sphere, strip, snowflake, or block.

[0049] Please refer to Figures 1 to 3 , optionally, the nozzle of the spray gun 30 sprays high-pressure liquid towards the liquid column 31 to cut the liquid column 31, obtaining a metal liquid column 32. At the same time, the ejected high-pressure liquid can also pre-cool the cut metal liquid column 32, preventing the atoms from arranging into an ordered crystal structure and keeping their disordered atomic structure arrangement to form an amorphous state, initially ensuring the shape of the metal liquid column 32. The liquid can be oil or water, and the oil can be mineral oil or synthetic oil. Adjust the supply speed, supply amount, and spraying angle of the liquid to control the cutting accuracy and the size and shape of the final metal liquid column 32.

[0050] Please refer to Figures 1 to 3 , optionally, the nozzle of the spray gun 30 sprays a mixture of high-pressure gas and atomized high-pressure liquid towards the liquid column 31 to cut the liquid column 31, obtaining a metal liquid column 32. At the same time, the ejected high-pressure mixture can also pre-cool the cut metal liquid column 32, preventing the atoms from arranging into an ordered crystal structure and keeping their disordered atomic structure arrangement to form an amorphous state, initially ensuring the shape of the metal liquid column 32. Adjust the supply speed, supply amount, and spraying angle of the gas-liquid mixture to control the cutting accuracy and the size and shape of the final metal liquid column 32.

[0051] In some embodiments, the liquid outlet hole is located at the bottom of the heating cavity, the liquid column 31 flows in the vertical direction, and the spraying direction of the spray gun 30 has an angle with the horizontal plane.

[0052] Please refer to Figures 1 to 3 , optionally, the range of the included angle can be -60 to 60 degrees. Based on the horizontal plane, when the spraying gun 30 sprays upward, the angle is positive, and at this time, the rotation angle of the spraying gun 30 is 0 to 60 degrees; when the spraying gun 30 sprays downward, the angle is negative, and at this time, the rotation angle of the spraying gun 30 is -60 to 0 degrees; when the included angle is 0, the spraying direction is perpendicular to the flow direction of the liquid column 31, so that the liquid column 31 can be cut into powder, snowflake, spherical, strip or block shapes.

[0053] In some embodiments, the cooling step includes preparing a cooling pool 20, which contains a coolant 21. The cooling pool 20 is located below the liquid outlet hole on the melting furnace 10, and the metal liquid column 32 drops into the coolant 21.

[0054] Optionally, the coolant 21 can be cooling water, cooling oil or liquid nitrogen, etc., to ensure that the metal liquid column 32 quickly dissipates heat and forms an amorphous structure. Through the coolant 21, the temperature of the metal liquid column 32 can be ensured to drop rapidly, with high cooling efficiency and better formation of the amorphous alloy 34.

[0055] It can be understood that a refrigerator can also be set to make the coolant 21 circulate, and in the process of circulating, it flows through the refrigerator and the cooling pool 20 in turn. The refrigerator can take away the heat in the coolant 21 to keep the temperature of the coolant 21 in the cooling pool 20 within a certain range.

[0056] Please refer to Figures 3 to 5 , in some embodiments, a liquid guide pipe 33 is prepared. The liquid guide pipe 33 is connected to the melting furnace 10 and communicates with the liquid outlet hole, and is used to guide the molten amorphous alloy raw material out of the heating cavity.

[0057] Please refer to Figures 3 to 5 , optionally, the liquid outlet hole is located at the bottom of the melting furnace 10, and the liquid guide pipe 33 is arranged in the vertical direction and can guide the liquid column 31 in the vertical direction, so that when the spraying gun 30 cuts the lower liquid column 31, the upper liquid column 31 can be kept stable, preventing the overall accidental fracture and shaking of the liquid column 31, so that high-quality amorphous alloy 34 can be obtained and the cutting efficiency can be improved. Moreover, the liquid guide pipe 33 has a certain length and can be spaced from the melting furnace 10 by a certain space, which is convenient for the installation of the spraying gun 30. The length of the liquid guide pipe 33 can be 20 cm, 30 cm or 50 cm.

[0058] In some embodiments, the liquid guide pipe 33 is rotatably connected to the melting furnace 10, and the liquid guide pipe 33 rotates a predetermined angle, such as 5 degrees, 10 degrees or 15 degrees, so that the cut metal liquid column 32 drops to different areas.

[0059] Please refer to Figures 3 to 5, optionally, the liquid guide pipe 33 is a straight pipe and the length direction thereof has an included angle with the vertical direction, and the included angle is greater than 0 and less than 90 degrees. A bearing can be provided at the upper end of the liquid guide pipe 33, so as to be rotationally connected to the melting furnace 10 through the bearing. By rotating along a certain conical surface through the liquid guide pipe 33, the metal liquid column 32 can be released in different areas of the cooling pool 20. Moreover, since the liquid guide pipe 33 is inclined, the liquid column 31 flowing out of the liquid guide pipe 33 has a certain bend relative to the vertical direction, which is beneficial to the cutting by the spraying gun 30.

[0060] Optionally, the liquid guide pipe 33 includes a fixed pipe section 331 and a rotating pipe section 332. The fixed pipe section 331 is arranged along the vertical direction and fixedly connected to the melting furnace 10 and communicates with the heating cavity through a liquid outlet hole. The rotating pipe section 332 is rotationally connected to the fixed pipe section 331 and deviates from the vertical direction by a certain angle. Thus, by the rotation of the rotating pipe section 332 relative to the fixed pipe section 331, the metal liquid column 32 can fall into different areas of the cooling pool 20.

[0061] Please refer to Figures 3 to 5 , it can be understood that during the cutting process, the liquid column 31 can rotate, so as to prevent too much metal liquid column 32 at a local position in the cooling pool 20 from affecting the cooling effect. At the same time, the metal liquid columns 32 of the same shape can also be dropped into the same area. For example, the strip-shaped metal liquid column 32 is dropped into the first area of the cooling pool 20, the snowflake-shaped metal liquid column 32 is dropped into the second area of the cooling pool 20, and the block-shaped metal liquid column 32 is dropped into the third area of the cooling pool 20. This is convenient for subsequent classification collection and improves the efficiency of collection and screening.

[0062] Please refer to Figures 3 to 5 , it can be understood that the spraying gun 30 can be installed on the liquid guide pipe 33 through a connecting piece, so as to rotate synchronously with the liquid guide pipe 33, or the movement of the spraying gun 30 can be controlled by a moving mechanism to make the spraying gun 30 rotate synchronously with the liquid guide pipe 33. The rotation of the liquid guide pipe 33 can be manually toggled with a tool or driven by a driving mechanism, such as a gear driving mechanism, a chain driving mechanism or a belt driving mechanism, which will not be elaborated here and can be selected according to the actual situation.

[0063] In some embodiments, the outer pipe wall of the liquid guide pipe 33 is wrapped with a heat-insulating material to prevent the temperature of the liquid column 31 from dropping during the outflow process and affecting the cutting. The material of the heat-insulating material can be glass wool or aerogel.

[0064] Please refer to Figures 3 to 5Optionally, the method for preparing the amorphous alloy further includes S4: screening, screening amorphous alloys 34 of different shapes. The prepared amorphous alloy 34 in the cooling pool 20 is taken out, and amorphous alloys 34 of different sizes and shapes such as spheres, powders, snowflakes or blocks are screened out using tools such as sieves or filters of different specifications and sizes.

[0065] Through the method provided in this application, high-temperature amorphous alloy liquid can be quickly cut to achieve efficient preparation of amorphous alloys 34 of different sizes and shapes. It has the advantages of low cost, high production efficiency, and easy operation, and is suitable for large-scale applications in industrial production.

[0066] The present invention also proposes an amorphous alloy 34, which is prepared by the above-mentioned amorphous alloy preparation method. The specific structure of the amorphous alloy 34 refers to the above-mentioned embodiment. Since the amorphous alloy 34 adopts all the technical solutions of all the above-mentioned embodiments, it also has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.

[0067] The amorphous alloy 34 provided in the embodiment of the present application has excellent performance and is lightweight, and has broad application prospects in the manufacturing field, such as mobile phone hinges, sensors, motors, transformers, etc. Among them, the amorphous alloy 34 provided in the present application can be applied to but not limited to the following fields:
