[0026] Next, in combination with the drawings and specific embodiments, the present invention will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be combined arbitrarily to form new embodiments.
[0027] Embodiment 1
[0028] Figure 1 is a flowchart of a method for manufacturing medium-entropy steel provided in Embodiment 1 of the present invention. This embodiment is applicable to the dynamic optimization of medium-entropy steel manufacturing parameters. This method can be executed by a medium-entropy steel manufacturing device, which can be implemented in the form of hardware and / or software, and the medium-entropy steel manufacturing device can be configured in an electronic device. As Figure 1 shown, the method includes:
[0029] S110. Control a laser metal deposition device to manufacture medium-entropy steel based on initial manufacturing parameters, and obtain the surface image and test results of the formed medium-entropy steel workpiece.
[0030] In this embodiment, the initial manufacturing parameters can be understood as the parameters used to control the laser metal deposition device for manufacturing, such as process parameters and iron element ratios. The laser metal deposition device can be understood as a device for manufacturing metal workpieces through laser. Medium-entropy steel can be understood as a new type of alloy material, and the content of different element characteristics will affect its hardness. For example, different iron element contents will result in different hardnesses of medium-entropy steel. The medium-entropy steel workpiece can be understood as a workpiece manufactured by a laser metal deposition device. The surface image can be understood as a high-frame-rate image of the surface of the medium-entropy steel workpiece. The test results can be understood as the results after testing the accuracy and performance of the medium-entropy steel workpiece.
[0031] Specifically, the processor can control the laser metal deposition device to manufacture medium-entropy steel based on the initial manufacturing parameters, and through the installed high-resolution industrial camera, monitor in real time in the LMD forming area to obtain the surface image of the formed medium-entropy steel workpiece. The processor can test the accuracy and performance of the medium-entropy steel workpiece through a testing device to obtain the test results.
[0032] Among them, the test results include the dimensional accuracy results and mechanical property test results of the medium-entropy steel workpiece.
[0033] In this embodiment, the dimensional accuracy results can be understood as the deviation results of the geometric dimensions of the medium-entropy steel workpiece. The mechanical property test results can be understood as the test results related to the material's own properties such as strength, toughness, and hardness.
[0034] Specifically, the combined dimensions of the medium-entropy steel workpiece can be measured by a coordinate measuring machine or a laser scanning device, and its deviation from the design model can be evaluated to test whether the dimensional tolerances of the key parts meet the requirements. The mechanical properties are tested by a material testing instrument (such as a tensile testing machine), for example, it can include strength, toughness, and hardness.
[0035] S120. When the test results do not meet the design requirements, determine the defect information of the medium-entropy steel workpiece according to the surface image and the test results.
[0036] In this embodiment, the design requirements can be understood as the accuracy and performance requirements of the workpiece. The defect information can be understood as the parts that do not meet the design requirements, such as the dimensions not meeting the requirements or there are defects in parts of the workpiece, etc.
[0037] Specifically, the processor can compare the test results with the design requirements. The test results should ensure that the medium-entropy steel parts meet the design requirements, and the performance test verifies whether the material has the set target performance indicators. By combining geometric measurement and microstructure analysis, the quality of the LMD formed parts can be comprehensively evaluated. When the test results do not meet the design requirements, the processor can analyze the surface image and the test results to locate the defect location and type, etc., constituting the defect information of the medium-entropy steel parts.
[0038] S130. Modify the initial manufacturing parameters based on the defect information, and control the laser metal deposition equipment to manufacture medium-entropy steel based on the modified manufacturing parameters. Continue to execute the steps of obtaining the surface image and the test results until the design requirements are met, and then obtain the final manufacturing parameters.
[0039] Specifically, the processor can determine the adjustment plan for the initial manufacturing parameters based on the defect information, and thus modify the initial manufacturing parameters. Then, control the laser metal deposition equipment to manufacture medium-entropy steel based on the modified manufacturing parameters, and obtain the surface image and the test results of the new medium-entropy steel parts to determine whether the medium-entropy steel parts manufactured this time meet the design requirements until the manufacturing parameters that meet the design requirements are obtained, so as to manufacture medium-entropy steel parts with better quality.
[0040] In the technical solution of the embodiment of the present invention, by controlling the laser metal deposition equipment to manufacture medium-entropy steel based on the initial manufacturing parameters, and obtaining the surface image and the test results of the formed medium-entropy steel parts; when the test results do not meet the design requirements, determine the defect information of the medium-entropy steel parts according to the surface image and the test results; modify the initial manufacturing parameters based on the defect information, and control the laser metal deposition equipment to manufacture medium-entropy steel based on the modified manufacturing parameters. Continue to execute the steps of obtaining the surface image and the test results until the design requirements are met, and then obtain the final manufacturing parameters. By establishing a closed-loop feedback control mechanism, real-time monitoring and adjustment are realized during the LMD processing, the manufacturing parameters are dynamically optimized, the dimensional accuracy and shape consistency of the medium-entropy steel parts are significantly improved, and the accuracy defect problem in traditional LMD manufacturing is solved.
[0041] Furthermore, on the basis of the above embodiment, the step of determining the defect information of the medium-entropy steel parts according to the surface image and the test results can be refined as:
[0042] Analyze the surface image through an image processing algorithm and combine it with the modeled defect database to determine the manufacturing defects of the medium-entropy steel parts; determine the accuracy defects based on the dimensional accuracy results and the medium-entropy steel design model; determine the mechanical defects of the medium-entropy steel parts according to the mechanical performance test results; determine the defect information of the medium-entropy steel parts according to the manufacturing defects, accuracy defects and mechanical defects.
[0043] In this embodiment, the image processing algorithm can be understood as an algorithm for image recognition, for example, it can include edge detection or pattern recognition, etc. The modeled defect database can be understood as a database including various types of defect data. For example, it includes real defect images (including different types of defects, such as cracks, holes, and lack of fusion, etc.); feature descriptions of defects (such as edge information, morphological features, and texture information); classification labels of defects (for pattern recognition and automated detection); it also includes defect data generated by simulation or manually labeled samples for training machine learning models. Manufacturing defects can be understood as defects in the manufactured parts that do not meet the design requirements due to processes, etc. during the manufacturing process. For example, it can include cracks, pores, discontinuous forming, and impurity inclusions, etc. Precision defects can be understood as defects in manufacturing precision. For example, it includes dimensional accuracy (the deviation of part dimensions from the tolerance range), shape accuracy (the deviation of geometric shapes (such as flatness, roundness) from the ideal form), and position accuracy (the error of the relative position of parts in space (such as coaxiality, parallelism), etc.). Mechanical defects can be understood as defects related to mechanical properties. For example, it can include insufficient yield, tensile strength, and hardness, or insufficient plasticity and unstable performance, etc. The design model can be understood as the most standard model and can be used as a dimensional reference. Defect information can be understood as the information formed by integrating all partial defects.
[0044] Specifically, the processor can analyze the surface image through the image processing algorithm and combine it with the modeled defect database to determine the type of defect to which the medium entropy steel part belongs and obtain manufacturing defects. The processor can compare based on the dimensional accuracy result and the medium entropy steel design model to determine precision defects. The processor can determine the mechanical defects of the medium entropy steel part according to the mechanical property test results and the set target performance indicators; and determine the defect information of the medium entropy steel part according to the manufacturing defects, precision defects, and mechanical defects.
[0045] Among them, the steps of determining the manufacturing defects of the medium entropy steel part by analyzing the surface image through the image processing algorithm and combining it with the modeled defect database can include:
[0046] Based on the image processing algorithm, defect detection is performed on the surface image to determine the defect area; based on the defect model, the defect area is matched and analyzed with the defect data included in the modeled defect database to determine the type of defect of the medium entropy steel part and obtain manufacturing defects.
[0047] In this embodiment, the defect area can be understood as the part of the surface image where there are defects. The defect model can be understood as the model used for retrieval in the modeled defect database. The defect type can be understood as the type to which the defect belongs.
[0048] Specifically, the processor can perform defect detection on the surface image based on an image processing algorithm, distinguish the background and defect areas included in the surface image. The processor can perform matching analysis on the defect area and the defect data included in the modeled defect database based on the defect model to determine the defect type of the medium-entropy steel workpiece and obtain manufacturing defects.
[0049] Exemplarily, a specific example is presented for illustration. Figure 2 FIG. is a defect example diagram in a medium-entropy steel manufacturing method provided in the first embodiment of the present invention, which is the result of recognizing a surface image through visual recognition technology (image processing algorithm), as Figure 2 shown. The upper left image is the result obtained by the image processing algorithm (including edge detection, morphological processing, or pattern recognition, etc.). Generally, this black-and-white contrast image is a binary image after enhanced contrast and grayscale conversion processing. Then, after denoising processing, threshold segmentation, and morphological processing, the defect contour is extracted, divided into black and white parts. The white part may represent the recognized crack or defect area, while the black part represents the background or non-defect area. This processing method can be used for automated defect detection and perform matching analysis through the defect model in the defect database to determine whether the defect type and determination accuracy meet the standards. The recognized result in the figure shows that the defect type is a crack.
[0050] Furthermore, based on the above embodiments, the step of correcting the initial manufacturing parameters based on the defect information and controlling the laser metal deposition equipment to manufacture medium-entropy steel based on the corrected manufacturing parameters, and continuing to execute the steps of obtaining the surface image and test results until the design requirements are met to obtain the final manufacturing parameters can be refined as follows:
[0051] Correct the process parameters in the initial manufacturing parameters according to the precision defects and manufacturing defects in the defect information; correct the iron element ratio in the initial manufacturing parameters according to the mechanical defects in the defect information; control the laser metal deposition equipment to manufacture medium-entropy steel based on the corrected manufacturing parameters, and continue to execute the steps of obtaining the surface image and test results until the design requirements are met to obtain the final manufacturing parameters.
[0052] In this embodiment, the process parameters can be understood as parameters related to the equipment manufacturing process, such as laser power: used to provide the energy required for melting the material; scanning speed: the speed at which the laser head moves, affecting the uniformity and cooling rate of the molten pool; powder feeding rate: the speed at which metal powder is transmitted through the nozzle. Among them, laser power is an important parameter that directly affects the temperature of the molten pool during the LMD process, and its change will affect the molding quality and the formation of defects. Too high laser power may cause the molten pool to overheat and melt too deeply, and high temperature may cause thermal cracks (such as liquefaction cracks); if the laser power is too low, the molten pool cannot fully melt the powder material, resulting in unfused defects and possible porosity. The scanning speed determines how fast the laser moves on the workpiece surface, which directly affects the shape, cooling rate and organizational structure of the molten pool. If the scanning speed is too fast, the shape of the molten pool becomes narrower and the molten pool cannot be fully expanded. If the cooling rate is too fast, it may cause residual stress to increase and cracks to occur. If the scanning speed is too slow, the molten pool becomes too wide, the material melts too much, and the cooling time is long, which may form a coarse grain structure and reduce material performance. The powder feeding rate determines the supply of metal powder in the molten pool. Its mismatch will lead to material waste or unstable molten pool. If the powder feeding rate is too high, too much powder will accumulate around the molten pool, causing the unmelted powder to aggregate, forming pores or inclusion defects, increasing the heat load of the molten pool, which may lead to prolonged cooling time, and then cause molten pool instability and defect expansion; if the powder feeding rate is too low, the metal powder supply in the molten pool is insufficient, which may lead to discontinuous forming, increased molten pool gaps and unfused defects.
[0053] In this embodiment, the iron element ratio can be understood as adjusting the iron content in the powder according to the alloy design requirements. The mechanical properties (such as strength, plasticity, and hardness) of medium entropy steel are significantly affected by the proportion of iron elements. A high proportion of iron elements will dilute the concentration of other alloying elements, resulting in a weakened solid solution strengthening effect, an increased tendency of grain coarsening, a reduction in the yield strength and tensile strength of the material, and an increase in plasticity, as well as a decrease in the hardness of the material; a low proportion of iron elements enhances the solid solution strengthening and precipitation strengthening effects, improves the strength and hardness of the material, but causes a decrease in the plasticity of the material; if the iron element is insufficient, it may affect the uniformity of the matrix structure, resulting in instability of performance.
[0054] Specifically, the processor can correct the process parameters in the initial manufacturing parameters according to the precision defects and manufacturing defects in the defect information. The processor can correct the iron element ratio in the initial manufacturing parameters according to the mechanical defects in the defect information. For example, when the mechanical defect is insufficient yield, tensile strength or hardness, the iron element ratio can be reduced; when the mechanical defect is insufficient plasticity or unstable performance, the iron element ratio can be increased. The processor can control the laser metal deposition equipment to manufacture medium-entropy steel based on the corrected manufacturing parameters, and continue to execute the steps of obtaining the surface image and test results until the design requirements are met, and finally obtain the final manufacturing parameters.
[0055] Among them, the step of correcting the process parameters in the initial manufacturing parameters according to the precision defects and manufacturing defects in the defect information can be refined as follows:
[0056] Correct the laser scanning range in the process parameters based on the precision defect; when the defect type in the manufacturing defect is a crack defect or a pore defect, correct the laser power in the process parameters;
[0057] When the defect type is discontinuous forming or impurity inclusion, correct the powder feeding rate in the process parameters.
[0058] Specifically, for precision defects, the processor can adjust the LMD process parameters, and the adjustment rules are as follows: if the dimensional accuracy is too large, reduce the laser scanning range; if the dimensional accuracy is too small, expand the laser scanning range; if the positional accuracy is insufficient, adjust the relative position of the substrate. For manufacturing defects, the processor can reduce the laser power and lower the scanning speed when the defect type is a crack; increase the laser power and increase the scanning speed when the defect type is a pore; increase the powder feeding rate when the defect type is discontinuous forming; when the defect type is impurity inclusion: reduce the powder feeding rate.
[0059] The technical solution of the embodiment of the present invention realizes real-time monitoring by acquiring the surface image and test results of the formed medium-entropy steel parts, and conducts defect analysis on the surface image and test results from multiple aspects, achieving a comprehensive evaluation of the size, material microstructure, and mechanical properties of the formed parts. When the parts do not meet the standards, the LMD process parameters are dynamically adjusted, and the adjusted laser power, scanning speed, powder feeding rate, and iron element ratio are input into the LMD equipment to continue generating medium-entropy steel parts, effectively optimizing the stability of the molten pool and the deposition accuracy, greatly improving the forming accuracy of the parts, ensuring the stability and consistency of the part quality, and using the closed-loop control method to feedback the adjusted process parameters to the manufacturing process in real time to achieve dynamic optimization. Finally, all forming parameters and iron element ratios are recorded to provide accurate reference data and experience support for subsequent manufacturing. It solves the accuracy and defect problems existing in the traditional LMD process, and also realizes continuous improvement through the feedback mechanism, providing a reliable and efficient technical route for the high-performance and high-precision manufacturing of medium-entropy steel parts, with broad industrial application prospects.
[0060] Exemplarily, on the basis of the above embodiments, a specific example can be used to elaborate on the overall steps of the method.
