Evolution Mechanisms of Microstructure and Performance of Aluminum Alloy Thin-Walled Components Repaired by Friction Stir Spot Welding
Taking the repair of prefabricated hole defects in 2024 aluminum alloy thin-walled components by friction stir spot welding (FSSW) as the research object, the evolution laws of microstructure and mechanical properties of FSSW-repaired joints of thin-walled components were clarified through process experiments and numer...
