Small particles like the Mg2Si prec

Small particles like the Mg2Si precipitates in Fig. 7 strongly impede the progress of recrystallization (Zener drag). Under extreme circumstances— large volumes of finely dispersed particles and very high strains— all motion of high-angle grain boundaries is suppressed, such that the entire dislocation energy that is stored in the microstructure during the preceding deformation can merely be released by extended recovery reactions, which is referred to as continuous recrystallization or recrystallization ‘in situ’ [35,38,39]. In less severely pinned cases the Zener inhibition may affect different recrystallization texture components in a different man- ner which is attributed to the different microstructural characteristics of the corresponding nucleation sites. In particular, it has been shown that dispersoids may selectively inhibit PSN, which, in turn, gives rise to a pronounced cube recrystallization texture notwithstand- ing that large particles are present in the material [37,40,41].{00 1}(31 0) (Fig. 10c) [31,37].
