. According to the results of ENGLER et al [1], a high recrystallization rate has been observed in Al-Mg alloy due to addition of element Mg. However, recrystallization during self-annealing... in other works [15-16]. One possible explanation is that the cross slip is obstructed because of the greatly reduced stacking fault energy in aluminum alloy 5182 due to the much high content of Mg element......
