description: In the course of research in this work, the method of manufacturing samples for TEM by cutting with a focused ion beam was improved. After conducting a detailed study using scanning and transmission electron microscopy, a number of new facts were noted that were obtained during a detailed study of a heat-resistant Fe-Cr-Ni-based alloy in a similar cast state, which directly affect the strength of the material. One of the main features of the hardening phases was the presence of fragmentation in both chromium and niobium carbide. At the same time, niobium carbide is a composite cluster in the center of which is aluminum oxide Al2O3, then a fragmented titanium nitride TiN is formed around it, followed by niobium fragments, thus forming a "matryoshka" of three phases that differ from each other, both in their elemental composition and in their crystal structure. Niobium carbide, which was considered the most stable in this alloy, has different modifications in the initial cast state: NbC, Nb2C, Nb6C5. The presence of pre-emissions in the austenitic matrix is shown. Structural changes that occur in the material after high-temperature exposure for a long time are also identified and described in detail. 2 hours at a temperature of 1150 Â° C. The presence of niobium carbides inside large chromium carbides was first shown. The presence of secondary carbides around the primary chromium and niobium carbides was found. After heat treatment, pre-emissions were preserved in the matrix, which indicates the further course of diffusion processes in order to balance the structure.
