Popis:	Changes in the structure of steel 10Kh9V2MFBR after creep tests are studied. It is shown that annealing causes inconsiderable changes in the structure of troostomartensite formed due to tempering in the head of a specimen. In the functional part of the specimen, on the contrary, the place of the initial troostomartensite is taken by coarse equiaxed subgrains; the density of the lattice dislocations decreases by an order of magnitude. The change in the microstructure in the process of creep causes a more than 30% decrease in the hardness of the material.
