The effect of particle-stimulated nucleation on texture banding in an aluminium alloy

Influence of Fe and Mn on the Microstructure Formation in 5xxx Alloys—Part II: Evolution of Grain Size and Texture

“…For the formation of the recrystallization structures, the PSN mechanism also needs to be taken into account, as the occurring fragmentation of primary phase particles during rolling can significantly increase the number of potential PSN nuclei (Figures 2, 3, 4, 5 and 6b), thus altering the resulting texture [21]. The PSN related texture component P was slightly more favorably observed for the low Mn alloys; in the case of the high Mn alloys, however, the expansion of the P-oriented nuclei is likely to be retarded by dispersoid pinning effects [23][24][25]68,69]. In general, it has to be emphasized that due to the overall weak textures the change of the annealing texture towards a higher random fraction of orientations through PSN effects is very weakly pronounced [6,58,59].…”

“…The resulting grain size is then related to the interparticle distances. Moreover, the PSN effect is commonly associated with changes in the typical recrystallization textures of Aluminum alloys [14,20,[22][23][24][25].…”

“…The typical Aluminum recrystallization texture can be altered by the presence of primary and secondary phases, due to the effects of PSN and Zener pinning. In the case of particle stimulated nucleation, the two specific texture components P {011}<122> and Cube ND {001}<310> are generally stated to preferentially evolve, together with a rather weak classical recrystallization texture [24,66,67]. Moreover, the Zener drag exerted by small dispersoid particles impedes the grain boundary movement and therefore changes the recrystallization texture by modifications of the oriented growth mechanisms.…”

The Dependence of Microstructural Evolution and Corrosion Resistance of a Sandwich Multi-Layers Brazing Sheets on the Homogenization Annealing

“…The homogenized microstructure may greatly affect the recrystallization behavior, grain size, mechanical properties and corrosion resistance of the final product [9]. D Different sizes of precipitated particles form during the homogenization annealing process, and they may influence the evolution of microstructure and texture [10]. Large particles (>1 or 2µm) promote recrystallization, and finely dispersed particles (<1µm) inhibit recrystallization [11].…”

Effect of solution time on microstructure, texture and mechanical properties of Al–Mg–Si–Cu alloys

“…According to the research on the recrystallization texture of AA6111 alloy, Chen et al [9] suggested that with increasing solution time, the deformation texture gradually decreases and the recrystallization texture increases firstly, and then decreases slightly, finally keeps unchanged. Saimoto et al [10] found that Cube orientation also exhibits the similar trend with increasing annealing time.…”
