| Shrnutí: | Title screen The paper presents the transmission electron microscope (TEM) investigations of the structure of Ni-Al-Crbased superalloy which is obtained by directional crystallization technique. The structural TEM investigations are carried out in two stages: 1) annealing at 1150°С for 1 h and 2) annealing at 1100°C for 480 h. The qualitative and quantitative analysis is given for the structure, phase composition and morphology of heat-resisting alloy additionally alloyed by rhenium Re both in the original state and after thermal treatment. The heat-resisting alloy comprises ~70 at % Ni, ~17 at % Al and ~5 at % Сr. The total amount of the primary alloying elements of Mo, W, Ta, Ti, Co, La was ~7 at % and 0.4 аt % Re. It is shown that the structure of the superalloy is represented by ([gamma]+[ gamma]¢)-phase mixture which has a morphologically correct crystallographic orientation and quasi-monocrystalline structure. σ-phase is formed in this superalloy due to rhenium. Since Re distribution in the alloy is not uniform, only a part of ([gamma]+[gamma]¢)-phase quasi-cuboids is distorted. It is shown that Re modification distorts the ideal structure of ([gamma]+[gamma]¢)-phase quasi-cuboids and results in the formation of [beta]-, [chi]- and [sigma]-phases.
