Microstructure and mechanical behavior of friction stir processed ultrafine grained Al–Mg–Sc alloy

► An equiaxed ultrafine grained microstructure was obtained via FSP. ► Very high fraction of high angle grain boundaries after FSP was obtained. ► FSP UFG alloy exhibited considerably high uniform elongation (∼14%). ► Observed grain size range in UFG alloy matched predicted Zener model values. ► Gra...
