Abstract

Abstract The eutectic composition powder of Al 2 O 3 –Y 3 Al 5 O 12 (YAG) was melted using a Mo crucible by induction heating. The melt was slowly solidified and resulted in a eutectic structure of large twinned crystals. The eutectic solid was ground and sieved into 3–44 μm and 64–124 μm powders. The powder was consolidated to reproduce eutectic composite by the spark plasma system (SPS). Mechanical properties of the consolidated eutectics were measured at room temperature. The high temperature strength was obtained from 1000 to 1400 °C. The consolidated eutectics was not plastically deformed at 1400 °C.
