Extraction residue analysis was conducted on reduced activation ferritic/martensitic steels, such as F82H-BA07 heat, F82H-IEA heat and JLF-1 JOYO heat. M-23 C-6 type precipitates, TaC precipitates and Fe2W Laves phase were identified in the present analyses. Precipitation was enhanced in gauge section of creep specimens tested at 550 degrees C under 162 MPa for 43.7 kh, and at 650 degrees C under 35.3 MPa for 37.5 kh. Z phase (CrVN) was not detected after the creep tests and after an additional aging at 700 degrees C for 100 h for the creep specimens.
