| Abstract: |
In the present work, aluminum-15 wt.% boron carbide-1.5 wt.% Co composite was prepared by microwave (660 °C) and spark plasma sintering (500 °C) and the mechanical properties and microstructure of sintered samples were compared. Samples prepared by spark plasma sintering obtained higher bending strength (382 MPa) and density (2.68 g/cm 3 ) compared to those prepared by microwave furnace (212 MPa and 2.41 g/cm 3 , respectively). XRD investigations indicated the decomposition of B 4 C and formation of Al 3 BC for microwave samples but not for SPS samples. The microstructure of sintered composites was examined and the uniform distribution of reinforced particles in the matrix was observed. [ABSTRACT FROM AUTHOR] |
