Study of Texture Change Due to Bending of Aluminum Alloy Sheets

Evolution of textural compositions in aluminum alloys during bending is studied. The change in crystallographic texture in billets and samples after bending of two materials is analyzed using X-ray diffraction. It is shown that bending leads to the formation of an anisotropic texture with a dominance of shear-type components. Particular attention is paid to the role of recrystallization nuclei in the reorientation of the grain structure. The relationship between texture evolution and mechanical properties of materials is also analyzed. It is experimentally established that the ductile A5 alloy is characterized by an ordered transformation of texture during bending. In contrast, in the high-strength 1565ch alloy, bending leads to texture blurring with an increase in the textureless fraction, which is due to the heterogeneity of deformation. The results of the study are of practical importance for predicting the mechanical properties of aluminum alloys after bending and optimizing the technological parameters of processing.
