Description	The material of trial rotor made of E911 steel underwent creep testing at temperatures from 500 °C to 600 °C. Three specimens crept at different conditions were selected for TEM investigation. Quantitative analyses of substructure and particles of secondary phases were performed. Microstructure corresponded to tempered martensite with ferritic laths subdivided into subgrains. Coarse M23C6 carbides occurred at grain and subgrain boundaries and fine vanadium nitride was present within grains. Recovery taking place during creep test at 500°C/250MPa/107,514 hrs resulted in decrease in dislocation density and increase in size of subgrains. Size of coarse carbides slightly increased. Important changes occurred after test at 575°C/155MPa/34,707hrs. Laves phase precipitated, mean size of coarse particles remarkable increased, dislocation density decreased while size of subgrains remained almost the same in comparison to the substructure after creep test at 500°C/335MPa/587hrs.
