Effect of second phase on mechanical properties and
High density Al 2 O 3 /SiC/YAG hybrid composites having an equiaxed second phase were fabricated in the temperature range from 1000 to 1800°C using SiC and Y 2 O 3 powders as additives. YAG (yttrium aluminum garnet Y 3 Al 5 O 12) was formed as the second phase from the reaction between Al 2 O 3 and Y 2 O 3 above 1400°C.
