Evaluation of the microstructural and mechanical properties of ductile cast iron and alloy steel dissimilar materials welded by magnetically impelled arc butt

The combined use of ductile cast iron and alloy steel is beneficial, however, this technique causes some difficulties in welding due to the different properties of these two materials. In the present work, magnetically impelled arc butt (MIAB) welding a solid-state joining process, was employed to w...
