抄録
Crack propagation tests of sintered silicon nitrode were carried out under sinusoidal cyclic load at elevated temperatures. The stress ratios used were 0.5 and 0.1, while the test temperature ranged from 1073K to 1273K. The main results obtained are as follows:<br>(1) Although the crack propagation rate with R=0.1 was higher than that with R=0.5 at 1073K, this tendency faded out at 1223K.<br>(2) The crack propagation rate at R=0.5 increased with temperature, while that at R=0.1 did not change with temperature.<br>(3) When the maximum stress intensity factor KImax decreased stepwise with R=0.1, the crack propagation rate decreased gradually, although KImax increased with crack length at each KImax revel.<br>(4) Slight oxidation started at 1073K. The grain boundary glassy phase softened at 1173K and Si3N4 crystal was attacked severely by oxygen in the atmosphere at 1273K.
