Mechanisms of grain refnement under multidirectional isothermal forging (MIF) at 325 °C (~0.65Tm) and the strain rate10−4s−1of the Al–Mg-based alloy with complex additions of transition metals were investigated. The starting alloy had anequiaxed grain structure with grain size 25 µm and a uniform distribution of coherent Al3(Sc,Zr) dispersoids of 20–50 nm. A distinguished structural feature in the early MIF stage was the formation of high strain- and misorientation gradients,followed by deformation banding. Due to the sequential changes of the loading axis, such bands were developed in variousdirections and fragmented the original grains. The number of bands and misorientation of their boundaries gradually rosewith strain, resulting in formation of (ultra)fne grain structure with the grain size 2 µm. New grain formation was concludedto occur via continuous dynamic recrystallization and controlled by the nanosized precipitates, which preferably remainedstable and coherent with the surrounding matrix.
