Abstract: Control rolling process of 6201 aluminum alloy was simulated on Gleeble-1500. The deformed specimens under different processes were analyzed by the observation of optical microscopy and TEM, and the measurement of hardness. It was shown that solid solution and aging treatment can be effectively combined in one procedure by control rolling process, the deformation temperature is ranging from 540℃to 200℃. Precipitation of Mg₂Si is accelerated by the rising of the finishing temperature, the amount of precipitates increases with holding time after deformation. A more uniformly distributed and finer Mg₂Si particles can be observed on deformed specimens which have been subsequently held at 250~300℃for 60s.
