Структурные изменения в жаропрочном никелевом сплаве при его модифицировании наночастицами тугоплавких соединений

Abstract

Influence of nanoparticles of titanium carbonitride on structure and properties of a heat resisting alloy is considered. It is shown that at modifying zones of transcrystallization in cast metal are eliminated, sizes of dendrites are abruptly descreased, the morphology and topography of phases is bettered what stipulates increased high-temperature strength of metal and high structural stability and continuous toughness of alloy.
