Abstract

The present study reports the specific features of texture formation in aluminum alloys during bending. Two aluminum grades, A5 with low alloy content and 1565 with high alloy content, were used to produce flat-rolled strips for bending. Both alloy workpieces were rolled following two thermal deformation processing practices, with different final annealing temperatures of 160 and 400°С, respectively. In the case of А5 alloy, the strips produced following both processing practices were bent successfully. In the case of the 1565 alloy, the workpiece produced with high-temperature annealing was bent successfully. However, the workpiece broke during bending after low-temperature annealing. Texture composition of the strip samples after rolling and bending was analyzed using X-ray texture analysis. The rolled strip grain structure was defined using optical microscopy. The crystallographic texture evolution during drawing was also simulated for the sampling point. The results show that recrystallization annealing occurred in both alloys at 400°С. A deformed structure was observed after heating the 1565 alloy. Analysis of the texture modification obtained by simulation and experiment demonstrates the tendency of the Cube component to Cu-texture transformation during bending. The Goss and L textures transformed into the Bs texture. Сu and P textures demonstrated stability without significant modifications during drawing.
