dc.description.abstractSlow crack growth behavior of two gas pressure sintered Si3N4 ceramics with different additives; a Yb2Si2O7 composition and an Al2O3-Y2O3 composition, was investigated by constant stress-rate ("dynamic fatigue") testing at 1400 degreesC. The slow crack growth parameter. n, was 14.7 and 6.3 for Si3N4 With Yb2Si2O7 and Al2O3-Y2O3 compositions, respectively. Superior crack growth resistance of Si3N4 with Yb2Si2O7 composition was due to its higher refractoriness of intergranular glassy films, compared to Si3N4 with Al2O3-Y2O3 composition.
