Applying an external field has been known to be a promising method to control the microstructure of materials, leading to their improved performance. In the present paper, the strengthening and toughening behaviors of some typical high-performance structural materials by coupling multi-physics fields, including electrostatic or electric-pulse, thermal, and stress fields, are reviewed in detail. In addition to the general observation that the plasticity of materials could be increased by multi external fields, their strengthening can also be achieved through controlling atomic diffusion or phase transformations. The paper is not limited to the strengthening and toughening mechanisms of the multi-field coupling effects on different types of structural materials, but is intended to provide a generic method to improve both the strength and ductility of the materials. Finally, future prospects about applications of multi external field have also been put forward based on the current works.
