Abstract: Local orientation analysis was used to investigate the continuous recrystallization process in a pure Al-1.3%Mn alloy with the emphasis on the influence of matrix orientations on the subgrain growth and precipitation. Results show that the differences of (mis)orientations in deformed matrices give rise to inhomogeneous subgrain growth and precipitation with respect to precipitate density and morphologies. Moreover, no apparent high angle grain boundaries were developed by accumulation of misorientations during subgrain growth.
