. "Material of trial rotor made of m,artensitic X12CrMoWVNbN10-1-1 steel underwent creep testing to the rupture in the temperature range from 500 \u00B0C to 600 \u00B0C. Microstructures of selected specimens tested at 500 \u00B0C and 575 \u00B0C that ruptured after exposures exceeding 100,000 hrs and 60,000 hrs, respectively, were studied in detail using light, scanning and transmission electron microscopy. Quantitative analysis of substructure was carried out. Tempered martensite consisted of ferritic laths with subgrains, coarse particles at grain and subgrain boundaries and fine intragranular precipitate. A significant increase in size of subgrains and a slight growth of coarse particles of secondary phases were found out after the test at conditions 500 \u00B0C/250 MPa/107,514 hrs, while volume fraction of particles was almost the same as in virgin material. Time to rupture was almost twice longer than it was predicted. Influence of microstructural changes on the creep strength is discussed."@en .
