Effect of Hot Rolling Rate on the Structure and Texture Condition of Plates of the Al – Si – Mg Alloy System

The method of orientation microscopy (EBSD) is used to study the structure and texture over the thickness of hot-rolled plate of aluminum alloy of the Al – Si – Mg system. In the surface layers of plates there are mainly shear components of the texture, and in the central layers a rolled texture is observed. With use of fast hot rolling rates alloy surface layers undergo recrystallization that substantially changes structure homogeneity over the plate thickness.
