Study of Microstructural and Mechanical Properties of Al/SiC/TiO2 Hybrid Nanocomposites Developed by Microwave Sintering

Aluminum hybrid metal matrix nanocomposites (Al/SiC/TiO2) were synthesized through a microwave-assisted powder metallurgy process, and their evolved microstructure mechanical properties investigated. The Al/SiC/TiO2 prepared by reinforcing aluminum (Al) with fixed amount of silicon carbide (SiC) nanoparticles (5 wt.%) varying concentrations titanium dioxide (TiO2) (3, 6, 9 wt.%). morphology results revealeda uniform distribution SiC TiO2 reinforcements in the matrix. An increase hardness compressive strength was noticed increasein nanoparticles. that had an optimum (9 showcased best properties, maximum increments approximately 124%, 90%, 23% microhardness (83 ± 3 HV), respectively, yield (139 8 MPa), ultimate compression (375 6 MPa) as compared to pure Al exhibited shear mode fracture during deformation process.
