Al–Mg–Si alloys are widely used in many fields due to their excellent comprehensive performance, but medium strength. Inorder to study the hot deformation behavior and microstructural evolution of Al–Mg–Si alloys, the isothermal compressiontests were carried out on the Gleeble-3500 thermal/mechanical simulation machine. The varying temperatures between 623and 773 K and strain rates of 0.001 s−1 to 1 s−1 with true strain of 0.51, 0.92 and 1.2 were considered. Strain-compensatedArrhenius model with modified friction was constructed and the correlation coefficient ( R ), absolute relative error ( AARE )between the experimental and predicted values reached to 0.998 and 1.95%. The results showed that, the critical stress ( c ) ofrecrystallization was reduced with increase in temperature and decreased strain rate. The softening mechanism by dynamicrecrystallization (DRX) was enhanced with the existence of dynamic recovery (DRV) and different DRX behaviors with differentmechanisms were identified and discussed. From the analysis of the microstructure after the friction was excluded, itwas observed that the texture was enhanced with large deformation with increased dislocation density. The strain hardeningeffect of deformation was stronger than the dynamic softening which led to the abnormal increase of stress.
