Abstract

Hot compression tests of Mg-3Al-1Zn magnesium alloy were performed at temperatures between 300-500 °C and strain rates between 0.03 and 90 s⁻¹. Dynamic recrystallization of the alloy is developed by the necklace mechanism. At the temperature of 300 °C, structures are fully dynamic recrystallized except at intermediate strain rates. As temperature rises to 400 °C, structures are fully recrystallized at all strain rates. The abnormal grain size increase at high strain rate is attributed to the temperature rising of the deforming sample.
