Summary

The effects of prolonged heating in flowing nitrogen and humidified air atmospheres on the course of degradation of two types of SiC ceramic fibers (Nicalon™) have been studied. The room temperature tensile properties of samples aged above 1200 d̀C were determined. Reaction was followed by measuring weight change, density, and compositional changes of the specimens after periods of exposure. Results are discussed with regard to the chemical composition and crystallinity of the starting materials.
