Investigation of the Intermetallic Compounds Fragmentation Impact on the Formation of Texture during the as Cast Structure Thermomechanical Treatment of Aluminum Alloys

In this work, the influence of intermetallic particle fragmentation during hot rolling as cast structure on evolution textures in aluminum alloys 8011, 5182 and 1565 was investigated. For purpose, laboratory multi-pass material carried out. At various degrees deformation, process stopped, metal quenched sent for optical electron microscopy to investigate large particles. addition, grain studied an X-ray analysis out order determine main texture components. Some samples were held at a temperature above recrystallization threshold then cooled air; composition also studied. simulation under modes alloys, taking into account The investigation showed that compounds with deformation degree 1.8, average, decrease size by 5–7 times. eutectic particles remaining after homogenization are drawn direction crushed, increasing their number accordingly. Therefore, most favorable stage formation nuclei is moment when they already numerous sizes much larger than subgrains. Simulation investigated considering factor as-cast significantly increases accuracy results.
