ALUMINIUM/STEEL JOINTS WITH DISSIMILAR THICKNESSES: ENHANCEMENT OF UTS AND DUCTILITY THROUGH MAKING AN S-SHAPED INTERFACE AND A MIXED-MODE FRACTURE

Aluminium/Steel Joints with Dissimilar Thicknesses: Enhancement of UTS and Ductility Through Making an S-Shaped Interface and a Mixed-Mode Fracture

This study presents a simple and innovative design to join a 2 cashel tail bag mm thick steel sheet to a 5 mm thick aluminium sheet in a butt configuration.Thickness differences were addressed using support plates, while an aluminium run-on plate was employed to prevent the FSW tool from plunging into the steel.The process produced a unique S-shape
