B4C reinforced aluminum composites were fabricated by microwave heating of the mixture of B4C (10, 15 and 20 wt%) and aluminum powders at 650, 750, 850 and 950 °C. The effect of different amounts of B4C on the microstructure and mechanical properties of aluminum matrix was examined. The maximum bending (238 ± 10 MPa) and compressive strength (330 ± 10 MPa) values were measured for composites sintered at 950 and 750 °C, respectively. The maximum hardness (112 Vickers) was measured for Al–20 wt% B4C composite sintered at 850 °C. XRD investigations showed the decomposition of boron carbide and also the formation of Al3BC by heating the composites at 850 °C. SEM micrographs showed uniform distribution of reinforcement particles in Al matrix. |
