Abstract
To determine the relations between rolling passes, mechanical behaviours and microstructure evolution of AA7050 aluminum alloys, finite element modeling of a multipass hot rolling process is developed and employed to investigate thermo-mechanical evolution during this processing. Through parametric studies, the distribution of local strain and temperature across thickness during the hot rolling process are numerically determined. These results are used to determine the subgrain size and thus the microstructure evolution during the hot rolling process are estimated.
