“…Considering preservation of nano-scale Al 3 (Sc,Zr) dispersoids (Fig. 3b), the softening effect was most likely attributable to the recovery and recrystallization in the weld zone, which eliminated the initial work-hardened microstructure [3][4][5][6]. Thus, the drastic grain refinement during FSW could not overbalance the substructure strengthening effect in the initial hot-rolled state.…”

a b s t r a c tIn this work, the effect of friction-stir welding (FSW) on the microstructure and cryogenic properties of an Al-Mg-Sc-Zr alloy was studied. The produced friction-stir joints demonstrated both excellent static and dynamic mechanical properties at cryogenic temperatures. The joint efficiency for the yield strength during transverse tensile tests was in the range of 95-100%, whereas the impacts fracture toughness in the stir zone was found to be superior compared with that in the base material. The high level of the mechanical properties was attributed to the preservation of Al 3 (Sc,Zr) dispersoids, extensive grain refinement and the breaking of the continuous grain boundary network of the coarse Al 6 Mn particles during FSW.
