HIGH TEMPERATURE PROPERTIES OF CERAMIC MATERIALS FOR USE IN GAS TURBINES

HOCHTEMPERATUREIGENSCHAFTEN VON KERAMISCHEN GASTURBINEN-WERKSTOFFEN

Reaction sintered Si//3N creeps much more strongly in air than in vacuum. This is attributed to internal oxidation of the porous material. Results of an attempt to establish the interdependence of pore size distribution, internal oxidation, and creep are plotted. The best results so far have been obtained when pore radii were largely below 0.05 mu m and the pore spectrum was narrow, so that a protective layer against internal oxidation was quickly formed. Creep in such material is minor.
