Friction Stir Spot Extrusion Joining With Its Metal Flow Investigation
Advances in Materials Science and Engineering, Volume 2025, Issue 1, 2025.This study aims to extrude a portion of an Al sheet through a steel hole shaped like a rivet to assemble an Al and a preholed steel sheet by a mechanical interlock. This will be accomplished by joining the two materials together. AA6061 and AISI1006 sheets were assembled using a lap arrangement, with the steel preholed sheet placed below the aluminum ...
