摘要: Abstract Oxide dispersion strengthened (ODS) ferritic alloys have a vast applicability due to their excellent mechanical resistance at high temperature. The precipitate of the nanoparticles in matrix has great effect on creep properties material; order study kinetics precipitation Y 2 Ti O 7 Fe–14Cr1W ODS alloy, annealing experiments were taken different temperatures (1050 °C–1400 °C) and for times (0.5–10 h), then these samples characterized by small-angle neutron scattering technique (SANS) under magnetic field TEM investigations microhardness measurements performed gather nanoscopic information about dispersed oxide particles size.
