Abstract

The composites were fabricated 61vol.% $\beta-SiC$ and 39vol.% $TiB_2$ powders with the liquid forming additives of l2wt% $Al_2O_3+Y_2O_3$ by pressureless annealing at $1700^{\circ}C,\;1750^{\circ}C,\;1800^{\circ}C$ for 4 hours respectively. The result of Phase analysis of composites by XRD revealed $\alpha-SiC$(6H), $TiB_2$, and YAG($Al_5Y_3O_{12}$) crystal phase. The relative density and the Young's modulus showed the highest value of 92.9701% and 92.884Gpa for composites by pressureless annealing temperature $1700^{\circ}C$ at room temperature.
