Going by the known reaction paths, a composition of boron carbide and silicon carbide in combination with aluminum was investigated at three different sintering temperatures in order to see the effect of boron carbide on mechanical properties of aluminum under conventional high temperature sintering conditions. The limited study on high temperature sintering using SiC and B 4 C showed gradual improvements in strength sintering above 750 ⁰C, which can be attributed to the in-situ formation of Si as well as SiB n , where n = 2, 4, 6 ….
