Description

Technical Field

[0001] This disclosure relates to the technical field of sample devices, such as a test module for directional solidification test samples and its supporting module. Background Technology

[0002] In modern materials science and engineering, the microstructure control of metallic and alloy materials has a decisive influence on their final properties. To obtain materials with excellent mechanical properties, thermal stability, and functional characteristics, researchers widely employ various advanced solidification control techniques. Among these, directional solidification technology has attracted considerable attention due to its ability to achieve ordered grain growth along specific directions. This technology precisely controls key parameters such as the temperature gradient, cooling rate, and solid-liquid interface migration speed during solidification, causing the molten metal to undergo directional crystallization along the opposite direction of heat flow, thereby obtaining columnar crystals or even single-crystal structures. It has wide applications in high-temperature alloys, magnetic materials, and semiconductor materials.

[0003] In directional solidification experiments, the directional solidification test module, as a key component supporting the sample and participating in heat transfer and motion control, directly affects the repeatability, accuracy, and reliability of the experimental results. However, common directional solidification test modules in related technologies have several limitations. On the one hand, most directional solidification test modules are only suitable for samples of a single size, lacking flexibility. When testing samples of different sizes or in batches, frequent replacement of the directional solidification test module or fixture is necessary, increasing operational complexity and time costs, and easily affecting the consistency of experimental data due to systematic errors introduced during replacement. On the other hand, traditional directional solidification test modules have relatively simple designs for sample positioning and fixation, making it difficult to achieve stable support for the sample. Especially under high temperature, high gradient cooling, or dynamic stretching conditions, the sample is prone to displacement, tilting, or even detachment, thus affecting the quality of solidified tissue formation. Therefore, directional solidification test modules in related technologies suffer from poor adaptability, complex operation, unreliable positioning and fixation, and a lack of multi-station synchronous experimental capabilities, affecting the repeatability, accuracy, and reliability of experimental results.

[0051] Combination Figures 1 to 6 As shown, this embodiment of the disclosure provides a support module 100 for a sample testing module 1000 used in directional solidification tests. The support module 100 includes a base 1, which has connection holes 11 of at least two different sizes. The support module 100 also includes support brackets 2 of at least two different sizes, the sizes of which correspond one-to-one with the sizes of the connection holes 11. Each support bracket 2 can serve as a workstation, with its bottom detachably inserted into the matching connection hole 11 and its top connected to the corresponding crucible 200.

[0052] The base 1 can be made of stainless steel, or other suitable materials. The base 1 is used to connect to an external drive device; for example, it can be connected to an external pull rod. The support bracket 2 serves as an intermediate connecting component between the base 1 and the crucible 200, providing support for the crucible. The crucible 200 is used to hold the metal sample, and its bottom is fitted to the top of the support bracket 2, allowing the top of the support bracket 2 to connect with the bottom of the crucible 200. Once the crucible 200 and the corresponding support bracket 2 in the bearing module 100 are detachably connected, a complete directional solidification test sample testing module 1000 is formed.

[0053] The bearing module 100 provided in this embodiment of the present disclosure, by setting at least two different sizes of connection holes 11 on the base 1 and configuring various sizes of support brackets 2 to match them, allows the bottom of the support bracket 2 to be detachably inserted into the corresponding connection hole 11 and the top to be detachably connected to the crucible 200. This design not only achieves flexible adaptation to crucibles 200 of different sizes, avoiding the cumbersome operation and systematic errors caused by frequently replacing the entire directional solidification test sample testing module 1000, but also improves the stability and repeatability of sample installation through modularity and precise matching of the structure. Especially under complex experimental conditions such as high temperature, high gradient cooling or dynamic stretching, it can effectively prevent the sample from shifting, tilting or falling off, significantly improving the accuracy and reliability of experimental results. At the same time, it provides a feasible technical basis for multi-station synchronous experiments, further expanding the functionality and application scope of the directional solidification test sample testing module 1000.

[0054] Each support holder 2 can be used as an independent workstation, enabling a multi-workstation layout. The multi-workstation design supports the directional solidification of multiple metal samples under the same experimental conditions, ensuring consistency in temperature gradient and tensile rate, and further improving experimental efficiency and data comparability.

[0055] In some embodiments, the base 1 includes a connecting shaft 12 and a support platform 13. A first end of the connecting shaft 12 is used to connect to an external drive device; for example, the connecting shaft 12 can be connected to an external pull rod. The support platform 13 is connected to a second end of the connecting shaft 12, and the support platform 13 is provided with at least two different sizes of connecting holes 11.

[0056] In some embodiments, a plurality of connection holes 11 are distributed around the geometric center of the support platform 13. This arrangement of connection holes 11 helps to ensure that the directional solidification test sample test module 1000 can remain balanced after the corresponding crucible 200 is installed in the support bracket 2 in each connection hole 11.

[0057] In some embodiments, the base 1 is provided with a plurality of first-type connection holes 11 and a plurality of second-type connection holes 11, wherein the inner diameter of the first-type connection holes 11 is larger than the inner diameter of the second-type connection holes 11. Here, the number of first-type connection holes 11 and second-type connection holes 11 can be determined according to actual design needs; for example, the number of first-type connection holes 11 is 5, and the number of second-type connection holes 11 is 3.

[0058] Multiple first-type connection holes 11 are arranged in an equally spaced circular array around positioning point A, where positioning point A is a virtual point. Positioning point A and the center points of the multiple second-type connection holes 11 are arranged in an equally spaced circular array around the geometric center of the support platform 13. The support module 100 includes first-type support brackets 2 and multiple second-type support brackets 2. The first-type support brackets 2 correspond to the first-type connection holes 11, and their bottoms are detachably inserted into the first-type connection holes 11; the second-type support brackets 2 correspond to the second-type connection holes 11, and their bottoms are detachably inserted into the second-type connection holes 11. Here, the number of first-type support brackets 2 is the same as the number of first-type connection holes 11, and the number of second-type support brackets 2 is the same as the number of second-type connection holes 11.

[0059] Because the inner diameter of the first type of connection hole 11 is small, the corresponding support 2 and crucible 200 are also small in size and mass. Combining multiple support 2s and crucibles 200 corresponding to the first type of connection hole 11 into a single assembly results in a total mass close to that of an assembly corresponding to a single second type of connection hole 11. In this case, arranging the positioning point A and the center points of the multiple second type of connection holes 11 in an equally spaced circular array around the geometric center of the support platform 13 ensures a uniform weight distribution of the support 2 and crucible 200 corresponding to the connection hole 11, guaranteeing the balance of the directional solidification test sample testing module 1000.

[0060] In some embodiments, the outer peripheral surface of the support platform 13 is provided with a groove 131. The groove 131 allows for the flow of cooling medium and helps maintain a stable cooling medium level. Optionally, the groove 131 is arc-shaped, and the number and size of the grooves 131 can be determined according to actual design needs. For example, there are 4-6 grooves 131, the depth of the grooves 131 is 2 mm to 5 mm, and the width of the grooves 131 is 5 mm to 20 mm.

[0061] In some embodiments, the connecting shaft 12 includes a first shaft segment 121, a second shaft segment 122, and a third shaft segment 123 coaxially arranged. The two ends of the second shaft segment 122 are connected to the first shaft segment 121 and the third shaft segment 123, respectively. The diameters of both the first shaft segment 121 and the third shaft segment 123 are larger than the diameter of the second shaft segment 122. This design allows an annular groove to be formed between the first shaft segment 121 and the third shaft segment 123. This annular groove can cooperate with the pull rod, enabling a secure connection between the connecting shaft 12 and the pull rod.

[0062] In some embodiments, the support 2 includes a first column 21, a second column 22, and a third column 23 coaxially arranged. The two ends of the second column 22 are connected to the first column 21 and the third column 23, respectively. The diameters of both the first column 21 and the third column 23 are smaller than the diameter of the second column 22. The first column 21 is detachably inserted into a matching connection hole 11, and the third column 23 is connected to a corresponding crucible 200.

[0063] The diameter of the first column 21 is smaller than that of the second column 22, thus forming a stepped structure between them. When the first column 21 is inserted into the matching connection hole 11, this step abuts against the top surface of the support platform 13, forming a mechanical limit and effectively preventing the support 2 from accidentally slipping or sinking in the axial direction. The diameter of the third column 23 is smaller than that of the second column 22, thus forming a stepped structure between them. When the third column 23 is connected to the corresponding crucible 200, this step abuts against the bottom surface of the crucible 200, forming a mechanical limit and effectively preventing the crucible 200 from accidentally slipping or sinking in the axial direction. Under complex working conditions such as high temperature, vibration, or dynamic tension, the limiting structure formed by the step helps to maintain a stable connection between the support 2 and the base 1, and between the support 2 and the crucible 200, avoiding axial displacement caused by sample gravity or external forces.

[0064] In some embodiments, the connecting hole 11 is a threaded hole, and the first post 21 is a threaded post. The first post 21 is threadedly connected to the connecting hole 11, thereby connecting the support bracket 2 to the connecting hole 11. The specifications of the threads of the first post 21 and the connecting hole 11 can be determined according to actual design needs. For example, the thread specifications of the first post 21 and the connecting hole 11 may include M4, M10, and M16, etc.

[0065] In this embodiment, the lengths of the first column 21 and the third column 23 can be determined according to actual design requirements. Here, the length of the first column 21 is between 5 mm and 10 mm, and the length of the third column 23 is between 3 mm and 8 mm.

[0066] Combination Figure 7 and Figure 8 As shown, this embodiment of the present disclosure provides a directional solidification test sample testing module 1000, which includes a bearing module 100 and a crucible 200. The crucible 200 is detachably connected to the corresponding support bracket 2 in the bearing module 100.

[0067] In this embodiment of the disclosure, the crucible 200 can be made of alumina, and the height of the crucible 200 can be determined according to actual design needs, for example, the height of the crucible 200 is 200 mm.

[0068] In this embodiment, the top of the support holder 2 is inserted into the bottom of the crucible 200, thereby achieving a detachable connection between the crucible 200 and the support holder 2. Specifically, the third column 23 of the support holder 2 is inserted into the bottom of the crucible 200, thereby achieving a detachable connection between the crucible 200 and the support holder 2.

[0069] In some embodiments, a gap of 0.1 mm to 0.5 mm is provided between the circumferential surface of the third column 23 of the support holder 2 and the inner wall of the connecting groove of the crucible 200, and the gap is filled with high-temperature adhesive. The high-temperature adhesive has a uniform thickness and covers more than 80% of the area of ​​the third column 23. The high-temperature adhesive can prevent the molten metal from flowing out after the sample melts due to gaps between the support holder 2 and the crucible 200.

[0070] In some embodiments, a ceramic pad is disposed inside the crucible 200. The ceramic pad is made of silicon nitride and has a thickness of 10 mm to 15 mm. The diameter of the ceramic pad is smaller than the inner diameter of the crucible 200, and the difference between the inner diameter of the crucible 200 and the diameter of the ceramic pad is between 0.5 mm and 2 mm. The ceramic pad serves as heat insulation, prevents the metal sample from sticking to the support holder 2, and ensures that the sample maintains a good condition during melting and solidification.

[0071] The following describes the usage process of the directional solidification test sample testing module 1000 in a real-world scenario:

[0072] 1. Insert the connecting shaft 12 of the base 1 into the pull rod to the top.

[0073] 2. Insert the corresponding support brackets 2 into each of the connection holes 11 of the base 1.

[0074] 3. Apply high-temperature adhesive evenly to the side of the third column 23 of each support 2 (the adhesive layer thickness can be 0.2 mm), press the bottom of each crucible 200 into the corresponding third column 23, and use a hair dryer to blow hot air to accelerate the curing of the high-temperature adhesive.

[0075] 4. According to the experimental requirements, select the crucibles 200 corresponding to the specified size, type and number of support holders 2, put the ceramic pad into the selected crucibles 200, and then put the metal sample into these crucibles 200.
