Precision control of microstructure variation and tensile properties in dissimilar friction stir lap welding joints using an adjustable tool

Abstract Friction-assisted plastic deformation at the joint interface is essential for achieving the desired joint properties in dissimilar friction stir lap welding (FSLW) of aluminum alloy (Al) with steel (Fe). This plastic deformation can be precisely controlled by using an adjustable tool, where...
