Description

Direct chill cast ingots of 3004 aluminum alloy were homogenized in the three conditions in order to vary the size and dispersion of α-Al(Fe, Mn)Si precipitates particle. The ingots were subsequently submitted to the single pass hot rolling by 50% reduction, and the rolled plates were held at exit temperature of 350-425°C. Subgrains form neither during rolling nor holding, in case where the ingots containing small particles in dense dispersion are rolled. On the other hand, the subgrain structure is formed during rolling, when the ingots having the relatively large particles in sparse dispersion are rolled. Moreover, recrystallization progresses and stops during holding, which results in the partially recrystallized structure. When the holding temperature gets higher, the recrystallization stops at the shorter time and the fraction of recrystallized area becomes larger. The recrystallization continues long, while the fraction of recrystallized area gets small, in case the solute content in matrix is large. These phenomena will depend on such factors as the driving force for recrystallization which decreases during holding, the pinning effect of particles and the migration velocity of the boudary of recrystallized grain.
