Pressureless Sintering of SiAlON Gas Turbine Components.

Abstract

Attempts were made to prepare Si(3-x)Al(X)O(x)N(4-x) beta' solid solution bodies by reacting X phase liquid and complimentary phase assemblages, and homogenizing these to single phase. Fully dense bodies were produced, but microstructural evidence suggested that some second phase material was retained in grain boundaries and controlled mechanical properties.
