The effect of iron and manganese on the recrystallization behavior of hotrolled and solution-heat-treated aluminum alloy 6013

Effect of Fe-Content on the Mechanical Properties of Recycled Al Alloys during Hot Compression

“…The recycled Al alloy containing 0.5 wt % Fe requires larger activation energy for dynamic recrystallization of the alloy with a lower Fe content, which may be due to the fact that the Al alloy containing a higher Fe content exhibits larger flow stress. This result is consistent with the report from Jeniski et al [18]: Fe-containing dispersed precipitates can increase the resistance for dislocation movements and dynamic recrystallization. It is noted that the activation energy of recycled Al alloy containing 0.1 wt % Fe is very close to the activation energy for bulk self-diffusion of pure aluminum, 142 kJ·mol −1 .…”

Correlation between Electrical Resistivity, Particle Dissolution, Precipitation of Dispersoids, and Recrystallization Behavior of AA7020 Aluminum Alloy

“…[2][3][4] In 6XXX-series aluminum alloys, the formation of different kinds of dispersoids, i.e., Zr-, Mn-, and Cr-containing dispersoids, which play the role of recrystallization inhibition, has been investigated. [5][6][7][8][9] In the case of 7XXX-series aluminum alloys, the formation of Zr-and Sc-containing dispersoids has been investigated. [10][11][12][13][14][15][16] For example, Robson et al [10,11] investigated the effect of Zr addition on the dispersoid formation and recrystallization fraction after hot deformation.…”

Microstructural Evolution During the Homogenization of Al-Zn-Mg Aluminum Alloys

“…Dispersoids exert a retarding force or pressure on low angle and high angle grain boundaries, which has a profound effect on the behavior of aluminum alloys in terms of recovery, recrystallization and grain growth [30]. A large amount of experimental research in addition to modeling efforts [15,20,[24][25][26][31][32][33][34][35][36][37][38][39][40][41][42] has been carried out to understand the conditions under which the dispersoids form and the effect of homogenization parameters on the evolution of dispersoids, with the aim of maximizing the effect of pinning the grain boundaries to retard recrystallization and grain growth. Most of the previous research [15,20,25,42] focused on Al 3 Zr as the only dispersoids present in the microstructures of the AA7xxx series aluminum alloys.…”

“…For example, in the AA3xxx series aluminum alloys, the formation of Mn-containing dispersoids and their effect on the recrystallization behavior were investigated [31][32][33]. In the AA6xxx series aluminum alloys, different kinds of dispersoids, i.e., Zr-, Mn-and Cr-containing ones were found to play individual roles in recrystallization inhibition [34][35][36][37][38]. In the case of the AA7xxx series aluminum alloys, the formation of Zr-and Sc-containing dispersoids has been investigated [15,20,25,42].…”
