| Summary: | Title screen The paper presents transmission electron microscopy investigations of Ni-Al-Co alloy with [gamma] and [gamma]-phases obtained by directional crystallization. The main alloying elements are Cr, Ta, and Re in the amount of no more than 3.5 аt % each. W and Mo are present in a smaller amount. The alloy structure is investigated in two states: (1) original (after directional crystallization and long-term homogenezation which includes a series of annealing ranging from 1285 to 1340°С) and (2) original state subjected to subsequent annealing within 900-1000°С temperature range during 105-1143 h. The experiments show that the annealing process causes the fracture of the ideal quasi-cuboid structure of the[gamma]-phase and modifies its preferable orientation. The increase in the annealing temperature modifies the morphology of the [gamma]-phase that, in turn, changes the grain orientation in the alloy.
