Key Points

High yield strength of 260.16 MPa was achieved after six passes of ECAP at 150°C, indicating optimal processing conditions for strength.
Increased elongation of 12.75% was noted after four passes at 200°C, demonstrating the effectiveness of temperature variations on ductility.
Microstructures were evaluated using optical and scanning electron microscopy, revealing significant grain refinement and deformation during ECAP.
Higher temperatures lead to grain coarsening, emphasizing the importance of temperature in modifying mechanical properties in aluminum alloys.
