Particle effects on recrystallization in magnesium–manganese alloys: Particle-stimulated nucleation Original Research Article

The influence of large (image diameter) particles on the recrystallization behaviour of magnesium alloys deformed in plane strain compression has been studied. Deformation zones characterized by a misorientation gradient were observed surrounding large particles, which were similar to those seen in other alloys where particle-stimulated nucleation (PSN) of recrystallization occurs. During annealing, new grains formed by PSN, but only at a small fraction of the coarse particles. Recrystallization was instead dominated by growth of existing dynamically recrystallized grains and nucleation of new grains from the deformed grain mantle region.
