Abstract

The work aims to investigate the influence of electron beam current on the microstructure and properties of welded joints during electron beam welding of 1J22/1Cr18Ni9Ti dissimilar metals. Electron beam welding was employed to join 1J22 soft magnetic alloys and 1Cr18Ni9Ti stainless steel dissimilar metals. The effects of electron beam current on the microstructure and properties of the dissimilar metal electron beam welded joints were studied by optical microscopy (OM), scanning electron microscopy (SEM), and mechanical property testing methods. Under all selected electron beam currents, dissimilar metal welded joints with excellent weld formation and free from welding defects such as cracks and porosity were obtained. The solidification mode of the dissimilar metal weld was the FA mode. Under this solidification mode, the primary δ-phase structure of the alloy exhibited a skeletal morphology, which could effectively inhibit the growth of γ-phase dendrites, resulting in grain refinement and reduced elemental segregation. Mechanical property testing results indicated that the beam current of 13 mA was the optimal parameter, with the tensile strength and elongation of the dissimilar metal welded joint reaching 839 MPa and 11.1%, respectively, equivalent to 121.3% and 13.6% of the 1Cr18Ni9Ti base material. In conclusions, 1J22 soft magnetic alloys and 1Cr18Ni9Ti stainless steel dissimilar metals demonstrate good adaptability to electron beam welding process. It is technically feasible to replace part of 1J22 soft magnetic alloys with lower-cost stainless steel in manufacturing applications.
