Nonuniformity of texture component and microstructure parameter distribution in the cross section of an alloy 8011 billet during hot rolling in a continuous group is studied. The study is performed by optical microscopy and x-ray diffraction analysis of microsections taken from hot-rolled strip in all stages of rolling in a hot-rolling mill continuous group. It is established that at first the texture is inhomogeneous over the thickness of a specimen, but it levels out in the hot rolling finishing passes. The results obtained are in good agreement with the theoretical concept of O. Engler in which the ratio of the components of the strain rate tensor I13/I11 is used to estimate the probability of appearance of a friction texture. Finite modeling using DEFORM 2D/3D software is used for theoretical analysis of the strain tensor components.
