The goal of ECAP method to resolve the issue of estimating the size of the thermal effect that develops in an AA5083 system during the deformation process. In order to do this, the process based on the mechanical and physical characteristics of metal subjected to upsetting and its temperature were analyzed using the Gleeble 3500 physical modelling complex. A database for modelling in the Deform-3D system was built based on the results. Additionally, the ECAP process was modelled, and thermal fields and the stress–strain state were examined. The difference in heating temperatures, while considering the sample's heat transfer to the tooling and when not, is no greater than eight percent. The complex strain-stressed situation can be simulated using this deformation scheme. Tests were performed on specimens that had been heated in a solution in water as well as specimens that had undergone extrusion and homogenizing processes, respectively. The solution treatment method does not affect the plasticity of the under examination alloy in the analyzed range of deformation parameters, but it does affect the hardness, microhardness distribution, and grain size of the alloy. TEM and electron backscattered diffraction analyses were used to explain the evolution of microstructure. The mechanical characteristics deteriorate and soften as a consequence of a rise in the deformation temperature. With equal channel angular pressing (ECAP) innovation, the AA5083 quality is being improved.
