The article describes a process of hot radial shear rolling of aluminum alloy 01570 studied using the QForm simulation software. The rolling process was carried out at 250, 300 and 400 oC in 4 passes from the original workpiece with a diameter of 42 mm and with elongation coefficients per pass of 1.92; 1.67; 1.99 and 1.47, respectively. The temperature analysis in the deformation zone during rolling showed that the intensity of the thermal effect of deformation was uneven, which led to a temperature gradient across the cross-section of the workpiece. Temperature of the material closer to the workpiece surface was higher than in the central zone. The highest temperature reached in this zone in the respective rolling passes is 427, 405, 381 and 364 oС. As a result, the thermal effect during rolling leads to a higher temperature of the workpiece after rolling than the original temperature. The study on the strain rate and equivalent strain also showed that the deformation process near the workpiece surface was more intense than in the central zone. The calculation of compressive stresses (stress triaxiality) showed that in every pass for the surface zone the minimum value of stress triaxiality was –3.17; –2.76; –2.76; –2.82, and the maximum value for the central zone was 0.56; 0.64; 0.74; 0.94. It has been experimentally established that such modes of deformation ensure the production of bars from the 01570 alloy without defects. The results of the experiments showed that the deformation by the radial shear rolling method led to strengthening of the material and the gradient formation of hardness over the cross-section. Hardness in the cross-section of the workpiece gradually increases from 98±3 to 116±3 HV in the direction from the central zone to the surface.
