Determination of Conditions for the Occurrence of Delamination, a Surface Defect Occurring during Hot Rolling of Aluminum Alloy Strips

Abstract The delamination defect occurring during rolling of aluminum alloys was studied. The defect was found to be formed due to the asymmetry of the deformation zone, and the factors influencing this phenomenon were described. The effect of these factors on the hot rolling deformation zone was analyzed using the Kolmogorov failure criterion.
