ABSTRACT In the current investigation was to examine how the microstructure of AA5083 changed under various processing settings and ECAP. Various heat treatments were examined to assess the alloy's workability under severe plastic deformity. However, moderate showed a strong tolerance to strain without failing. Considering both cases with and without the implementation of back pressure and the microstructure stability of thermal effect after subjecting the material. The study encompassed microstructure analysis, texture characterization, and evaluation of mechanical properties for the temper, this significantly improved the material's ductility and strength. An exceptional level of ductility, reaching 95% was achieved under specific conditions of a temperature of 210°C and a strain rate of 10 −4 s −1 . The textures that resulted from this treatment were examined in connection with the material's mechanical behavior. The microstructure was assessed using the Electron Backscatter Diffraction technique, which allowed for a thorough examination of the grain structure. The grain refinement increased with the number of Equal Channel Angular Pressing passes, leading to an enhancement in the alloy's strength. It was found that increasing the pressing temperature during the third pass decreased the creation of new grains and increased the average grain size. The achievement of grain refinement in the AA5083 was thoroughly examined in this study shedding light on the relationship between temperature and microstructural evolution. Researchers used the Electron Backscatter Diffraction technique to examine how high temperatures affected the AA5083's grain refinement during Equal Channel Angular Pressing. The microstructural development and the impact of temperature on the Equal Channel Angular Pressing process were the main subjects of the investigation, at how the alloy reacted to high temperatures and grain refining.
