MODELING THE STRUCTURE EVOLUTION DURING HOT ROLLING OF ALUMINUM ALLOYS USING THE DEFORM SOFTWARE

Abstract

The investigation of the structural evolution of aluminum alloys during hot rolling is a pertinent challenge in modern metallurgy. This study involves the modeling of the process of aluminum alloy structure formation during hot rolling using the DEFORM-3D software suite. The software allows for the replication of real rolling conditions and the prediction of changes in alloy structures. The article presents modeling of evolutionary structures during the hot rolling of aluminum alloy 5182 BT (Al-Mg 4.5%) in a five-stand continuous hot rolling mill. The DEFORM-3D software product was used for mathematical modeling, and the Johnson-Mehl-Avrami-Kolmogorov equation was employed to account for recrystallization kinetics. The results of calculations yielded the volume of recrystallized grains and their sizes throughout the entire rolling process. However, it is crucial to note that changes in grain sizes during the rolling of aluminum alloys are a complex process and do not follow a constant pattern. This is due to the influence of numerous factors related to both the metal's internal structure and the specific technological processes. Therefore, the modeling results require further verification through industrial experiments. In this context, data regarding the evolution of texture and structure obtained during forced hot rolling "2800" with subsequent thread cooling of the metal were used for comparison. In conclusion, this article contributes to a deeper understanding of processes occurring during the hot rolling of aluminum alloys and provides valuable insights into the impact of recrystallization on the final structure and material properties.
