| Abstract | High density (>98%T.D.) SiC-AlN composites were obtained by means of a pressureless sintering process which did not require the powder bed to protect sample against weight loss. Sintered sample showed a fine microstructure formed by 2H SiC-AlN solid solution with Y10Al2Si 3O18N4 as grain boundary phase. Mechanical properties (hardness, toughness and flexural strength) were determined and compared to the properties of SiC-AlN sample obtained with different sintering processes (hot pressing, gas pressure sintering, pressureless sintering with powder bed). Microstructural analysis confirmed that a mullite scale protects material against oxidation up to 1400°C. |
