Test Methods and Properties of Materials


The recrystallization processes taking place in a silicon nitride-base material produced by the hotpressing technique were studied by the methods of metallography and electron microscopy. It is shown that the starting grains of such a material become comminuted as a result of hot pressing. This is accompanied by partial recrystallization, which has a localized character. The number of large grains is negligible, and these grains have no significant effect upon the process of structure formation in the material.
