“…With energy conservation and emission reduction, 6061(AlMg1SiCu) aluminum alloy forged wheels have been extensively used in automobile industry due to the overall performance [1][2][3][4][5]. The aluminum forged wheels made it possible to ensure grain flow parallel to the main force lines by precisely adjusting the part geometry to the forging process [6][7].…”

The formation of coarse grains is easy to occur during the mass production of 6061 aluminium alloy forged wheels. The coarse grains and uneven grain structure will lead to the reduction and instability of the mechanical properties of the wheels, which will affect the fatigue strength, corrosion resistance and impact toughness of the wheels. In this paper, the effect of solution temperature and solution time on the coarse-grained formation of 6061 forged wheel was studied. The reasons and mechanism of coarse-grained formation were revealed by advanced materials characterization techniques such as scanning electron microscope, electron backscattering diffraction and transmission electron microscope. The results show that the deformation causes a large number of dislocation pile-up and entanglement in the grain, forming a large number of small angle sub-grains, and the heating process of sub-grains has more interfaces, which provides the driving energy for the abnormal grain growth.

“…Its feature is that the deformable element of the wall of the workpiece, due to the fact that the gap is smaller than the thickness of the workpiece, is subject to thinning [1][2][3][4]. This ensures the geometric accuracy of this workpiece element and increases its strength characteristics [5][6][7][8].…”

“…Few studies in this field were carried out without taking into account the features of deformation of square blanks and under the assumption that the material is isotropic [5][6][7][8]. Consideration of anisotropic properties opens the way for a more rational design of technological processes, improving the quality of products, reducing the labor intensity of manufacturing, and saving metal [9][10].…”

Plastic forming, in many cases, includes the drawing of hollow cylindrical products as the main operation. For the manufacture of such products, round blanks are used as semi-finished products. However, during the blank production from strips or tapes, their geometry causes a very significant metal loss. A very effective way to reduce metal loss is to replace round billets with square ones. The use of square blanks gives an additional increase in the height of the products. In this regard, the article investigates the drawing of a square blank into a cylindrical die. The research was carried out on the basis of the analysis of experimental work and computer modeling. According to the results of the research the rational ratios of the geometric dimensions of the tool and workpieces are found.
