✦ Synopsis

For composite materials such as metal-oxide, metal-ceramics, etc., the formation process of grain microstructure has been theoretically considered from the macrokinetic point of view. The interaction (mainly a thermal one) between two immiscible phases during crystallization was studied. Various types of grain-size distribution were found and distinguished. A comparison with an experimental metallographic specimen of a metal-oxide system was made. Self-propagating high-temperature synthesis was used to produce the material ingots. Limits to the use of the model proposed are revealed.
