Fig. 3 Schematic diagram of the necklace DRX mechanism of Mg matrix composites with necklace-type particle distribution: a particles distribute along the grain boundaries; bPDZs are formed along grain boundaries; c DRX preferentially occurs along the initial grain boundaries due to PSN; d DRX extends from intergranular areas of initial grains to initial transgranular areas; e DRX is completed.Reproduced from [96], with permission from Elsevier

Fig. 4 Schematic illustration of DRX influenced by submicron SiCp during hot deformation: a microstructure before DRX, b high-density dislocations around submicron SiC particles, c DRX nucleation priority near submicron SiC particles and at grain boundaries, d microstructure after DRX.
