“…During the FSW of the AA5083-H111, the low heat input during the welding process (solid state welding process) has a much lesser effect on HAZ compared to the fusion welding process. Additionally, the grain refinement and strain hardening occurring during the FSW process in the SZ [ 62 , 63 , 64 ] improve the FSW joints’ UTS more than the fusion welding joints. Congruently, the reduction in E% for FSW joints is expected ( Figure 7 ).…”

“…Our uniaxial tensile results have shown [16] that post-ageing treatment can cause the mechanical properties of CoreFlowed 6082 Al wires to change in a wide range, which provides us with a path to tailor their mechanical properties over a wide range.…”

“…Recently, a sub-surface treatment technology developed by the Welding Institute (TWI) with the help of a friction stir processing (FSP) mechanism [14], named CoreFlow TM , is a very promising method for the preparation of alloy wire. Particularly, the CoreFlow TM technique has been proved to produce Mg alloy wires [15], and Al alloy wires [16] from materials with poor extrudability in our previous studies. During the CoreFlow TM process shown in Fig.…”

“…The FSE is an advanced solid-state technique for metal chips processing, since the reached temperature are around 400 °C, and it is a direct-recycling process, since there is no longer the need to recast the chip to recreate a new billet to be extruded, thus avoiding the problems typically due to the fusion processes: dendritic structure, cracks, hot oxidation, and shrinkage phenomena during solidification. Another important characteristic of the FSE process is the possibility to greatly refine the microstructure of the extruded pieces with respect to the traditional extrusion process [ 1 , 12 , 13 ].…”
