A study of precipitation and recrystallization behaviour of aluminium alloy AA1235

Evolution of microstructure and mechanical properties during annealing of cold-rolled AA8011 alloy

“…Many researchers have observed the precipitation of Fe from supersaturated Al-Fe solid solution and subsequent interaction with recrystallization [12][13][14][15][16][17][18]. Present researchers have reported elsewhere the evidence of precipitation and recrystallization taking place simultaneously during isothermal annealing of cold-rolled alloy AA1235 [19]. The possible precipitation reaction can be interpreted by the variation of electrical resistivity with the annealing temperature (Fig.…”

A Preliminary Study of the Phase Transformations in Rolled Al-Fe-Si Alloy

“…In contrast, Aghaie-Khafri [14] examines the microstructure and formability of homogenized and nonhomogenized AA8011 alloy under deformation, and Ryu and Lee [15] study the effect of precipitation on the evolution of recrystallization texture in AA8011 alloy sheet. Also in this interpretation has been useful the work of Roy et al, [16] who combine measurements of DSC, transmission electron microscopy, and orientation imaging microscopy (OIM) to study the behavior of the precipitation and their interaction with the recrystallization in an AA1235 alloy whose proportions of Fe and Si are different from those of the AA8011 alloy.…”

Recrystallization Behavior of Commercial Purity Aluminium Alloys

“…The evidence of dislocation pinning and restriction of subgrain growth is examined for a commercial purity aluminium alloy (AA8011) after annealing below 400ºC [23]. Similarly, the welldefined subgrains are examined in another commercial purity aluminium alloy (AA1235) after 4h annealing at 250ºC [24], as shown in Fig.4. The dislocation density change is clearly examined at some portions (X) of boundaries.…”

“…Even after a long time of high temperature annealing for heavily deformed alloy, the Al 3 Fe particles may pin down the dislocations, resulting in the presence of a large amount dislocations inside the grains (Fig. 7) [3,24]. During the intersection of grain boundary by particles, a Zener drag force is generated to restrain the boundary migration [49].…”
