• MGC (Melt Growth Composite) materials, in-situ single crystal oxide ceramic eutectic composites such as Al_2O_3/YAG, Al_2O_3/GAP and Al_2O_3/EAG are expected to be one of the ultra-high temperature structural materials. In this paper, the mechanical properties of high-temperature strength, fracture toughness, and fatigue crack growth resistance were discussed. The tensile creep test for Al_2O_3/YAG binary eutectic composite was conducted at 1873K in air. It was found that normal creep curves which had the primary creep region and the secondary creep region were distinctly observed. It was also found that the creep resistance for Al_2O_3/YAG binary eutectic composite was dependent on the loading direction and the tensile creep resistance was smaller than the compressive creep resistance. Comparing with other advanced high temperature structural materials at their usable temperature, the Al_2O_3/YAG binary eutectic composite had similar creep resistance to the advanced ceramic materials even at 1873K.
