Abstract

Much attention has been paid to unidirectionally solidified ceramic composites as candidates for high-temperature structural materials. We have recently developed potential ceramic eutectics, which are named Melt Growth Composites (MGC). The Al2O3/GAP(GdAlO3) binary MGC has a novel microstructure, in which continuous networks of single-crystal Al2O3 phases and single-crystal GAP phases interpenetrate without grain boundaries. Chain structure in the Al2O3/GAP binary system is formed due to the frequent branching of both phases resulted in the entangled structure. Therefore, the Al2O3/GAP binary MGC has excellent high-temperature characteristics in the air atmosphere at very high temperatures. In the paper, high temperature strength, thermal stability of microstructure and strength, and fracture toughness of the Al2O3/GAP binary MGC are reported.
