Mechanical Behaviors of Friction Stir Spot Welded Joints of Dissimilar Ferrous Alloys under Opening‐Dominant Combined Loads

Advances in Materials Science and Engineering, Volume 2014, Issue 1, 2014., 2014
Mechanical properties and failure behaviors of friction stir spot welded (FSSW) joints of two dissimilar ferrous alloys, cold‐rolled carbon steel (SPCC) and 409L stainless steel (SUS 409L), are investigated under opening‐dominant combined loads. The texture of dissimilar FSSW joints depends on the upper sheet material. The failure contours for the FSSW
