Abstract:Numerical simulation on microstructural evolution during multipass hot-rolling of aluminum alloys was performed by using DEFORMTM software and incorporating Zener-Hollomon parameter Z. The distributions of equivalent stress, equivalent strain, equivalent strain rate and temperature, as well as the distribution of recrystallization fraction through the thickness of deformed specimen during multipass hot-rolling of 5182 aluminum alloy, were all calculated. The results agree well with the metallographic examination of the deformed specimen on Gleeble 1500.

 

Key words: 5182 aluminum alloy; multipass hot-rolling; microstructural evolution; FEM numerical simulation
