Solid State Bonding Mechanics In Extrusion And FSW: Experimental Tests And Numerical Analyses

Abstract

In the paper the authors compare the different solid state bonding mechanics for both the processes of hollow profiles extrusion and Friction Stir Welding (FSW), through the results obtained from a wide experimental campaign on AA6082‐T6 aluminum alloys. Microstructure evaluation, tensile tests and micro‐hardness measurements realized on specimens extracted by samples of the two processes are discussed also by means of the results obtained from coupled FEM simulation of the processes.
