Modern requirements for aluminum alloys used in mechanical engineering and aviation include increased strength characteristics and refined microstructure. One of the promising methods for improving the properties of aluminum alloys is rolling on a three-high skew rolling mill, which provides intense plastic deformation and a fine-grained structure. This study describes the results of numerical modeling of the rolling process of aluminum alloy 6082 rods in a three-high skew-type mill. Numerical modeling of alloy 6082 was conducted using the ForgeNxT 2.1 software designed to simulate metal-forming processes, including rolling. The rheological behavior of the material under study was investigated by compression tests using a Gleeble 3800 plastometer ("DSI", Austin, TX, USA), which enabled the determination of the main parameters of material flow under specified conditions. The process of rolling bars of alloy 6082 on a three-high skew mill was numerically analyzed in the temperature range of 350-400 °C. This allowed for the study of the distribution of stresses, temperatures, and strain rates from the rolling mode. A physical experiment was conducted to validate the results of numerical modeling. The obtained results enabled the identification of rolling modes that promote microstructure refinement and enhance the mechanical properties of the alloy.
机械工程和航空领域对铝合金的现代要求包括提高强度特性和细化微观结构。改善铝合金性能的一种有前景的方法是在三辊斜轧机上轧制，这种轧制能产生强烈的塑性变形并形成细晶组织。本研究描述了6082铝合金棒材在三辊斜轧机上轧制过程的数值模拟结果。使用专门用于模拟包括轧制在内的金属成型过程的ForgeNxT 2.1软件对6082合金进行了数值模拟。通过使用Gleeble 3800热模拟试验机（美国德克萨斯州奥斯汀市“DSI”公司）进行压缩试验，研究了所研究材料的流变行为，这使得能够确定特定条件下材料流动的主要参数。在350 - 400°C的温度范围内，对6082合金棒材在三辊斜轧机上的轧制过程进行了数值分析。这有助于研究轧制方式下应力、温度和应变速率的分布。进行了物理实验以验证数值模拟结果。所获得的结果能够确定促进微观结构细化和提高合金力学性能的轧制方式。
