Abstract
To clarify the effect of Mg content on annealing textures developed in Al–Mg alloys during high temperature annealing, Al–Mg alloys containing up to 9 wt.% Mg in supersaturated solid solution were cold rolled 95% and isothermally annealed at 450 °C. Their textures were investigated with the orientation distribution function analysis. It was found that, in the recrystallization textures observed at complete recrystallization, addition of more than 1 wt.% Mg was sufficient to suppress the development of {100}<001>. With increasing Mg content, {100}<001> decreased remarkably, whereas {100}<013> and {103}<321> increased. Thus, {100}<013> and {103}<321> were found to be the main orientations of the recrystallization textures of Al–Mg alloys annealed at high temperatures. {100}<013> developed most remarkably at 4 wt.% Mg, while {103}<321> showed the maximum development at 7 wt.% Mg. During subsequent grain growth at 450 °C, remarkable texture changes were observed only in the alloys containing Mg in the range between 2 and 4 wt.%. In these alloys, {100}<013> developed at the expense of {100}<001> at earlier stages of grain growth, whereas {103}<321> increased independently of these two orientations at later stages of grain growth. Reflecting these texture changes, grain growth occurred in these alloys discontinuously. Such a discontinuous grain growth with large texture changes is expected, if strong textures are already present before grain growth, and if recrystallized grains having similar orientations are distributed by forming large clusters before grain growth.
