Effect of Magnetic Field on the Microstructure and Mechanical Properties of Inconel 625 Superalloy Fabricated by Wire Arc Additive Manufacturing

•The magnetic field has been applied during the Wire Arc Additive Manufacturing (WAAM) processing of Inconel 625 in this work.•The mechanism that the effect (grain refinement effect and element segregation inhibition) generated by magnetic field on the microstructure was discussed.•The application of magnetic field during WAAM process effectively improves the mechanical properties of Inconel 625 alloy.
