System and Method for Detecting and Regulating Microstructure Online with Electromagnetic Assistance

The disclosure belongs to the field of metal additive manufacturing, and specifically discloses a system and a method for detecting and regulating a microstructure online with an electromagnetic assistance. The system comprises a forming device, a detecting device, a regulating device and a substrate, wherein, the forming device, the detecting device and the regulating device are located above the substrate, the detecting device is connected with the regulating device, and the regulating device comprises an electromagnetic shock regulating unit and an electromagnetic stirring regulating unit; in operation, a workpiece may be formed layer by layer on the substrate through the forming device, the detecting device performs a real time detection for the microstructure in a formed area, and transmits a detection result to the regulating device, and according to the detection result, the electromagnetic shock regulating unit may be used to perform the electromagnetic shock on a newly formed fused micro area, or the electromagnetic stirring regulating unit may be used to perform the electromagnetic stirring on a molten pool to regulate the microstructure of the workpiece. The disclosure may control grain size and reduce defects such as pores and incomplete fusion during a forming process, and has advantages of closed loop regulation, stability, and strong pertinence.
