N2 - Extraction residue analysis was conducted on reduced activation ferritic/martensitic steels, such as F82H-BA07 heat, F82H-IEA heat and JLF-1 JOYO heat. M23C6 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 ÌŠC under 162 MPa for 43.7 kh, and at 650 ÌŠC 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 ÌŠC for 100 h for the creep specimens.
