Texture Development in Aluminum Alloys with High Magnesium Content

The evolution of texture in the AlMg6Mn0.7 (1565 ch) alloy throughout entire cycle its thermomechanical treatment has been studied. Using this as an example, a new way is shown to control development, which applicable alloys with high magnesium content. An integrated approach applied, including optical and electron microscopy, well X-ray diffraction analysis, determination mechanical properties modeling using algorithms crystallographic plasticity theory. All stages have studied, namely development deformation structure out as-cast reversing hot-rolling stand, continuous hot rolling, cold rolling final recrystallization annealing. study showed that second phase particles are main source nuclei at all temperature treatment. importance these increases when Zener-Hollomon parameter increases. To obtain maximum possible proportion random texture, processing must be carried parameters. However, should not interfere complete process same time. After annealing temperatures equal or greater than 350 °C, large formed, metal almost isotropic.
