Abstract
This study investigates the effects of the Cyclic Extrusion Compression (CEC) process and sintering on the microstructure, mechanical properties, and tribological behavior of Al-SiC-graphite composites. The process involves dual plastic deformation, which incorporates both the extrusion and compression phases. The CEC process refines the microstructure and improves the uniformity of the reinforcement particle distribution. Enhanced grain boundary density and dislocation transformations contribute to increased hardness (55 HV1) and compressive strength (633 MPa), with optimal results achieved after two to four cycles of CEC. Sintering further improves densification (95.65 %) and stabilizes the coefficient of friction but slightly reduces mechanical strength and wear resistance due to recrystallization and oxide formation (Al2O3). Tribological analysis reveals that CEC cycles enhance wear resistance and reduce weight loss (0.25 % after four cycles), while sintering stabilizes friction but marginally increases wear rates. The combined effects of SiC particles, acting as wear-resistant barriers and graphite, serving as a solid lubricant, contribute to improved composite performance. These findings highlight the importance of optimizing CEC cycles and sintering conditions to achieve superior mechanical and tribological properties.
