“…7 that the microhardness at the centric position of the welding NZ is the highest, up to 110 HV ~ 120 HV. The microhardness of the part of the HAZ is the worst, which is due to the growth grain size in the HAZ under the thermal cycle caused by the FSW processing, resulting in a decrease in the mechanical properties of the area [10][18] [19]. In summary, the microhardness of the HAZ is the worst, which is the lowest hardness of the overall material, and the part of the NZ is where the microhardness is highest.…”

“…7, the microhardness of RS of the HAZ is obviously higher than that of the AS in the welding direction in processing. Hwang et al concluded, Because the temperature of the RS welding is lower than that of the AS, the AS have more heat to HAZ to crystal grain growth, resulting in a lower hardness of the RS after welding relative to the AS of the welding [19][20][21].…”

The connection of new energy vehicle batteries often involves a copper soft connection. In this experiment, Friction Stir Welding (FSW) of multilayer copper foils (TU1) were proposed for the research of copper soft connection. It studies the correlation between microhardness profiles, conductivity test data, welding morphology and process parameters. When the rotation speed increased from 300,600,900,1200 rpm to 1500 rpm, the copper color of the weld changes, and the welding morphology is better at the parameter of 900 rpm-80 mm/min. Elongated grains were processed into fine equiaxed and recrystallized grains by FSW. Continuous dynamic recrystallization (CDRX) was the main restoration mechanism responsible for the microstructural evolution in the NZ. After 900 rpm-80 mm/min FSW of multilayer copper foils, the hardness of the welding zone increases 23 HV and the conductivity decreases 22 IACS. After friction stir welding, the hardness value is the opposite trend of ω/v changes, and conductivity value is the similar change trend of ω/v changes in the NZ.

“…As a solid-state welding process, FSW causes less distortion and changes in metallurgical and mechanical properties compared to conventional fusion processes (Mishra and Ma, 2005;Mishra, Partha and Kumar, 2014). The transversal tool movement produces an intricate material flow pattern, which varies depending on the following parameters: tool geometry and workpiece penetration, heat flow, tilt angle, rotational and transverse speed (Chao et al, 2003;Galvão et al, 2010;Leal et al, 2008;Sun et al, 2013;Velichko et al, 2016).…”

Friction stir welding is a multipurpose solid-state joining process mainly used for aluminium and steel plates and frames. Friction stir welded non-ferrous metallic alloys, similar or dissimilar, in particular aluminium alloys, provide opportunities for the improvement and developement of new product designs. This paper investigates the correlation between the mechanical behaviour and morphological structures of friction stir welded Al-Mg-Si(Cu) alloy plates in two temper conditions. Micro Vickers hardness and tensile tests were carried out. Additionally, morphology was investigated using optical microscopy and scanning electron microscopy. Samples subjected to the post weld heat treatment were shown to have the best properties owing to the formation of a significant number of hardening particles which, added to the nugget grain refinement, resulted in the increase of the material strength.
