Three Mg–Al–Zn alloys (AZ31, AZ61 and AZ91) were subjected to plane-strain compression at different temperatures (200 and 400 °C) and strain rates (10−2 and 10−4 s−1). The effect of second-phase precipitates on the texture evolution was investigated. It was found that a high level of Mg17Al12 precipitates impeded extension twinning and enhanced dynamic recrystallization, resulting in weak deformation textures.
