Abstract :Present study aimed to increase the applicability of the material in the aviation, aerospace, and automotive industries by improving the microstructural and tribological properties of Al6063 alloy using the ECAP technique at room temperature with different passes (2, 4 and 8) and by selecting the BC route. XRD, SEM, EDS/Mapping, 3D Profilometer, TEM and TEM/MapViewer methods were performed on all samples in the microstructural characterization processes. Microhardness and dry sliding wear tests were conducted to evaluate the mechanical and tribological properties. It was determined that with the number of passes being 8, the hardness of the equiaxed sub-micron/nano grains increased to 119HV and had the best tribological properties (CoF: 0.398 and Ra: 0.620).
