Abstract

Sialon material doped with a mixture of yttrium and cerium in a molar ratio of 1 to 3, up to a total amount of 6 wt% has been investigated with high resolution transmission electron microscopy (HREM). Theα-sialon crystals were shown to contain defects of types not previously reported. These include stacking faults, shear and coherent intergrowth ofα- andβ-sialon crystals. For some of the defects structural models are proposed and verified by image simulations.
