Hot deformation behavior of the 3003 Al alloy was investigated by conducting hot compression tests at various temperatures (300-500 A degrees C) and strain rates (0.0l-10.0 s(-1)). A constitutive equation was established to describe the flow behavior. The apparent activation energy of the 3003 Al alloy was determined to be 174.62 kJ center dot mol(-1), which is higher than that for self-diffusion in pure Al (165 kJ center dot mol(-1)). Processing maps at a strain of 0.6 for hot working were developed on a dynamic materials model. The maps exhibit a flow instability domain at about 300-380 A degrees C and 1.0-10.0 s(-1). Dynamic recrystallization occurs extensively in the temperature range of 450-500 A degrees C and at the strain rate of 10.0 s(-1). The optimum parameters of hot working for the 3003 Al alloy are confined at 500 A degrees C and 10.0 s(-1) with the highest efficiency (37%).
