Abstract

The strength of ceramic materials shows commonly a great scatter. If the material exhibits distinct subcritical crack growth additionally a great scatter in lifetime occurs at least under tensile loading. Gas pressure sintered siliconnitride is expected to show a less distinct fatigue behaviour as sintered Siliconnitride. Therefore, experimental investigations under dynamic, static and cyclostatic loading with 4-point bending specimens at 1250°C in air were performed.
