Effect of primary recrystallization texture on abnormal grain growth in an aluminum alloy

Grain growth was studied in aluminum alloy samples with two different recrystallization textures. One sample with a pronounced cube texture showed abnormal grain growth upon annealing at 500 °C. Another sample with an almost random texture obtained through clock rolling and subsequent recrystallization annealing showed regular grain growth. The differences in grain growth behavior are attributed to differences in the amount and distribution of high- and low-angle grain boundaries caused by the two different recrystallization textures.
