Description

Technical Field

[0001] The present invention belongs to the technical field of amorphous alloy 3D printing, and in particular relates to a method for forming a zirconium-based amorphous alloy complex component based on laser powder bed melting. Background Art

[0002] Amorphous alloy (also known as metallic glass) is a new type of metal material developed in the middle of the last century. The atomic structure of amorphous alloy is in a state of short-range order and long-range disorder. Therefore, it has a series of mechanical, physical and chemical properties that are significantly superior to traditional crystalline alloys, such as high strength (>1500 MPa), high elasticity (elastic limit>2%), high toughness (Kq>100 MPa·m 1 / 2 ), excellent corrosion resistance (in Cl -1 The corrosion resistance in the environment is more than 100 times that of stainless steel) and soft magnetic properties (iron loss is only 1 / 4 of silicon steel), so it has broad application prospects in the fields of machinery, energy, chemical industry and military. Amorphous alloy is a metastable material, and a sufficiently high cooling rate is required from the melt solidification process to avoid the formation of crystalline phase. The formation of amorphous alloys requires a very high cooling rate, but the traditional preparation technology is affected by its own heat dissipation capacity, resulting in a slow cooling rate. It is easy to form a brittle crystallized phase during the forming process, which makes it difficult to form large-scale complex components, and therefore cannot meet the needs of industrial applications.

[0003] The laser powder bed fusion forming technology developed in recent years is a new manufacturing technology based on the principle of layer-by-layer material accumulation. It can transform complex three-dimensional processing into simple two-dimensional processing, greatly reducing the difficulty of manufacturing complex components. This technology has high forming accuracy and fast cooling rate, and is particularly suitable for the forming and manufacturing of amorphous alloys. It is expected to solve the manufacturing problems of complex components that cannot be completed by traditional processing technology, and find a new way for the application of amorphous alloys in engineering. Although a higher cooling rate can better form amorphous alloys, it is inevitable that a higher cooling rate will cause instability in the molten pool, thereby causing deformation, cracks and other phenomena, resulting in the failure of complex component forming. Therefore, the optimization of laser powder bed fusion forming process parameters and the structural optimization of complex components have an important influence on the forming quality and amorphous rate of zirconium-based amorphous alloys.

[0004] The zirconium-based amorphous alloy formed by laser powder bed fusion has almost no plasticity at room temperature, and large thermal stress will be generated inside the complex components during the forming process. As the printing size continues to increase, the thermal stress accumulation will exceed the threshold of crack initiation, causing deformation and cracks in the complex components. The cracks caused by stress concentration and thermal stress accumulation have greatly limited the development and application of zirconium-based amorphous complex components formed by laser powder bed fusion. Therefore, there is an urgent need for a method to solve the cracking and deformation of zirconium-based amorphous alloy complex components by laser powder bed fusion, and to regulate the stress of complex component forming. Summary of the invention

[0005] In order to overcome the shortcomings of the above-mentioned prior art, the purpose of the present invention is to provide a method for laser powder bed fusion forming of zirconium-based amorphous alloy complex components, so as to solve the technical problems that the prior art is prone to cracking and deformation when preparing zirconium-based amorphous alloy complex components by laser powder bed fusion forming, and cannot perform stress regulation during the forming of complex components. In order to achieve the above object, the present invention adopts the following technical solutions: The present invention discloses a method for forming a complex zirconium-based amorphous alloy component based on laser powder bed melting, comprising: Step 1: Construct a three-dimensional model of the complex zirconium-based amorphous alloy component to be processed; Step 2: Simulate the temperature field and stress field of the 3D model during the laser powder bed fusion molding process and calculate the thermal stress; Step 3: Analyze the thermal stress calculation results, and then design large plane structures, cantilever beams and micro structures for complex components of zirconium-based amorphous alloys to obtain a complex component model of zirconium-based amorphous alloys after structural correction; Step 4: Slice and layer the zirconium-based amorphous alloy complex component model after structural correction, set process parameters, and select scanning strategies to obtain a set slice model; Step 5: Import the set slice model into the laser powder bed fusion forming equipment for forming processing, and then undergo heat treatment and impurity removal to obtain a zirconium-based amorphous alloy complex component.

[0006] Preferably, in step 3, for the large plane structure of the zirconium-based amorphous alloy complex component, a lattice filling structure is designed based on stress matching calculation; for the cantilever beam and microstructure of the zirconium-based amorphous alloy complex component, balanced stress distribution is achieved by optimizing the supporting structure.

[0009] Further preferably, the supporting structure adopted by the cantilever beam structure is a triangular bracket structure.

[0010] Further preferably, the support structure adopted by the microstructure is a rod structure.

[0011] Preferably, in step 1, the software used to construct the three-dimensional model of the complex zirconium-based amorphous alloy component to be processed is UG, SolidWorks or Catia.

[0012] Preferably, in step 4, the structurally corrected zirconium-based amorphous alloy complex component is imported into a slicing software for processing, and the slicing software is Autodesk Netfabb Ultimate or Magics.

[0013] Preferably, in step 4, the process parameters are set as follows: the spot diameter of the laser is 20-50 µm, the power is 60-180 W, the scanning rate is 600-1800 mm / s, the layer thickness is 20-40 µm, the scanning spacing is 20-70 µm, the overlap rate is 30%-40%, the preheating temperature is 50-80°C, and the oxygen concentration in the printing environment is less than 300 ppm.

[0014] Preferably, in step 4, the scanning strategy includes raster scanning, chessboard scanning, island scanning, etc.

[0015] Preferably, in step 5, the heat treatment method is low-temperature annealing, and the heat treatment temperature should be at least 50°C lower than the crystallization temperature of the material; the impurity removal treatment includes removing support, surface grinding and cleaning the surface of the product obtained by the forming treatment.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The method for forming a complex zirconium-based amorphous alloy component based on laser powder bed fusion disclosed in the present invention, on the one hand, can obtain the stress concentration parts of the complex component that are prone to cracks and deformation during the laser powder bed fusion forming process by simulating the temperature field and thermal field during the laser powder bed fusion forming process and calculating the thermal stress. This process provides guidance for structural optimization design and avoids the problem of cracking and deformation of the complex zirconium-based amorphous alloy component during the processing process. On the other hand, heat treatment can eliminate the residual stress inside the complex component, and support removal after heat treatment can effectively prevent the residual stress from causing cracking and deformation of the complex component.

[0017] Furthermore, the present invention adopts a dot matrix filling optimization structure to eliminate stress concentration in a large plane structure and avoid cracking and deformation caused by accumulation of thermal stress during printing.

[0018] Furthermore, the present invention adopts an optimized support structure to achieve an average stress distribution of cantilever beams and microstructures of complex zirconium-based amorphous alloy components, thereby avoiding deformation caused by the accumulation of thermal stress during the printing process.
