[0058] An information collection module 500 is used to collect and monitor the forming process and parameter information during the solidification process of the metal material;

[0059] The host computer 600 is used to receive and display the information collected by the information collection module 500, and is also used to process and analyze the displayed information and compare it with preset parameters to obtain output parameters;

[0060] The host computer 600 is also used to control and change the current and magnetic field;

[0061] The wire 800 is used to connect the above modules and to pass current and magnetic field into the molten pool 100 .

[0062] In a specific embodiment, the system further comprises:

[0063] A manual module 700 is used to manually adjust material properties and process production using the output parameters;

[0064] In a specific embodiment,

[0065] A conductor 800 is laid in the molten pool 100, and the current input device 200 and the magnetic field input device 300 are connected to the molten pool 100 through the conductor 800 to pass current and magnetic field into the molten pool 100;

[0066] In a specific embodiment, the conductors are in the form of thin wires or thin ribbons, and the conductors 800 are laid in the molten pool 100 at a certain angle or in parallel. Figure 2 As shown, the molten pool 100 can be meshed;

[0067] In a specific embodiment, the wires can be connected or slightly staggered up and down and not connected, ensuring that the current on each wire can be independently controlled, the types of current and magnetic field can be adjusted, and the current and magnetic field can act independently or be coupled with each other;

[0068] In a specific embodiment,

[0069] The wire is a semiconductor wire;

[0070] The thickness of the wire is selected based on feasibility, cost, laying density and the degree of impact on the metal material;

[0071] The material of the wire is selected according to the properties of the metal material to be solidified;

[0072] In a specific embodiment, the laid conductors can be regarded as composite fibers in a metallic material.

[0073] In a specific embodiment,

[0074] The current input device passes a direct current or a pulse current into the molten pool;

[0075] In other specific embodiments, the current input device feeds other current into the molten pool;

[0076] The magnetic field input device introduces a pulsed magnetic field, an alternating magnetic field or a composite magnetic field into the molten pool;

[0079] The action form of the current and magnetic field passed into the molten pool 100 can be adjusted by the host computer 600. The host computer 600 is connected to the current input device 200 and the magnetic field input device 300, and can control the size, direction and type of the current and magnetic field passed into the molten pool 100.

[0080] In a specific embodiment, the material adding module adds the additional material to the molten pool at an appropriate time before solidification or during the metal solidification process;

[0081] In a specific embodiment, the added material is a hydrophilic substance of the metal material or a dispersed phase material of the metal material, a magnetic substance and metal particles;

[0082] Preferably, the added material is some substance that is sensitive to electric current and magnetic field;

[0083] In a specific embodiment, the adding parameters of the adding material module 400 can be repeatedly adjusted by the host computer 600 until the required adding parameters are found.

[0084] The present application regulates the metal material forming process through electric and magnetic fields. By controlling the size, direction and type of the current and adding a variable magnetic field to the molten pool, the metal particles in the free state can migrate under the action of the current and magnetic field, interfering with the formation of the organizational phase during the crystallization process to form the required organizational structure, and then regulating the organizational morphology and composition during the metal material forming process. Combined with the upper computer's adjustment of the addition parameters, different materials are added until the required additional materials are found, and the output parameters of the preset metal material are obtained, thereby achieving fine control of the material's microstructure and producing materials with excellent performance.

[0085] In a specific embodiment, an information collection module 500 is also distributed on the wire 800 laid in the molten pool 100;

[0086] In a specific embodiment, an information collection module is distributed on each grid divided by the wires;

[0087] In a specific embodiment, the information acquisition module is a nanoelectronic material or sensor with monitoring function;

[0088] In a specific embodiment, the information acquisition module monitors the forming process during the metal solidification process, including monitoring the local temperature of the metal material, the direction and form of particle and fluid movement, and the formation of organizational phases, etc. It can also monitor the concentration, movement and crystallization of particles in the molten pool, etc., which is equivalent to the effect of a microscope to some extent;

[0089] In a specific embodiment, the host computer 600 is connected to the information acquisition module 500. The host computer 600 receives data from the information acquisition module 500, processes, analyzes and displays the data, and compares the data with preset parameters, thereby outputting parameters or adjusting the current, magnetic field and added materials through the host computer.

[0090] This application receives data from the information acquisition module through the host computer to adjust the current, magnetic field and added materials and display the material forming process, finds suitable parameters to form the required metal material, and finally obtains the output parameters. The obtained output parameters are the input parameters required to form the target material. This application adopts a cyclical approach to explore and obtain the optimal output parameters, thereby realizing fine control of the microstructure and composition of the metal material.

[0091] Another embodiment of the present application also provides a method for finely controlling the microstructure and composition of a metal material, such as Figure 2 Shown, including:

[0097] If the requirements are not met, other additives are added to the molten pool, and the current and magnetic field are changed by the host computer, and the above steps S50-S70 are performed in sequence until the information displayed by the host computer meets the requirements, and then the parameters are output;

[0098] In a specific embodiment, the method further comprises:

[0099] S90. Use the output parameters to manually and precisely adjust material properties and process production.

[0100] Since electric current and magnetic field have a great influence on the metal crystallization process, they can cause free metal particles to migrate, thereby adjusting the crystal morphology, size and solute, etc. Therefore, the present application adds certain affinity substances of the material or other dispersed phase materials in the alloy (such as certain magnetic substances, or materials sensitive to electric current and magnetic field) in a timely manner while passing electric current and magnetic field through the molten pool, artificially intervenes in the formation of the material's microstructure and components, improves the material performance, and cooperates with the monitoring and precise adjustment of input conditions of equipment such as information acquisition modules and host computers to improve efficiency and repeatedly test to find a more optimized solution to achieve fine control of the material's organizational properties.

[0101] The present application provides a system and method for finely controlling the microstructure and composition of metal materials, which can more finely control the microstructure and composition of materials, and then can formulate the required properties, and cooperate with corresponding new processes to develop new materials with excellent performance; it can also be used to develop new material organizational properties, use electric and magnetic fields to control the material forming process, cooperate with information collection materials and computers and other advanced equipment for monitoring and adjustment, find the corresponding affinity substances for different materials, or the dispersed phase suitable for adding to the alloy, to form the system parameters of the synthetic material; it can also monitor the change process of the microstructure morphology, which is convenient for the research of metal materials.

[0102] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description.
