Влияние состояния расплава на структуру жаропрочных сплавов типа ЦНК

Abstract

В жидком состоянии изучены температурные зависимости удельного электросопротивления и кинематической вязкости литейных высокохромистых жаропрочных никелевых сплавов типа ЦНК. Рассмотрены вопросы структурообразования при затвердевании. Исследовано влияние параметров плавки на макроструктуру и механические свойства литого металла. Технология с использованием высокотемпературной обработки расплава и термоциклирования позволяет получить литые изделия из жаропрочных сплавов, обладающие дисперсной дендритной структурой, меньшим объемом карбидной фазы, большей плотностью и удовлетворительной микроструктурой. The temperature dependences of electrical resistance and kinematic viscosity of TsNK type cast superalloys have been investigated. The questions of structure formation during solidification have been considered. The influence of parameters on melting process on macrostructure and mechanical properties of cast metal has been studied. Using of high-temperature melt processing and temperature cycling in melting technology allows to produce cast parts from superalloys with dispersed dendritic structure, smaller volume of carbide phase, higher density and satisfactory microstructure.
