| Abstract: |
| Electromagnetic pulse (EMP) treatment introduces EMP energy into materials or components by applying electric pulse or magnetic pulse, so as to modify the microstructure, shape,mechanical property, and service performance of the materials or components. In this study, the mechanism of EMP treatment was investigated by analyzing the influence of EMP on the microstructure and mechanical properties of materials,and the research progress of relevant basic theories was reviewed.The EMP processing technology was summarized from the perspectives of EMP assisted molding manufacturing, EMP heat treatment, and EMP micro-defect healing.The future research direction in the field of EMP was pointed outin terms of the micro-mechanism of EMP technology, the simulation research of EMP,and the research of coupled electric and magnetic pulse treatment. |
