摘要：

3003 Al alloy samples with various metallurgical qualities were obtained by various melt-treatment methods and were deformed by isothermal compression in the deformation temperature range of 300 degrees C to 500 degrees C at strain rates between 0.0l and 10.0 s(-1) with a Gleeble-1500 thermal simulator. The results show that there is a close relationship between melt-treatment and subsequent thermal deformation. The hot deformation activation energy (Q) bears a linear relationship with the inclusion content (H) of 3003 Al alloy prepared by various melt-treatment methods, that is Q = 35.62 H + 171.58. The activation energy of the 3003 Al alloy prepared by the highly efficient melt-treatment is the lowest (174.62 kJ center dot mol(-1)), which is beneficial to the material hot plastic deformation. The critical strain of the 3003 Al alloy prepared by various melt-treatment methods is investigated through the work hardening rate. Finally, the critical conditions of the investigated alloy were determined to predict the occurrence of dynamic recrystallization.
