　　Nowadays,advanced nuclear power plants(NPPs)are designed to produce more electricity with less fuel at high temperature.This requires the structural materials to possess excellent mechanical properties and high corrosion resistance.Addition of Al can improve the corrosion resistance of oxide dispersion strengthened(ODS)steels.However,Al reacts with Y2O3 to form large Y-Al-O particles in the steels and deteriorates their mechanical properties.Herein,we directly added Y2Ti2O7 nanoparticles(NPs)into the Fe-Cr-Al ferritic steel to substitute the conventional Y2O3 NPs by mechanical alloying(MA).The Y2Ti2O7 NPs transformed into amorphous-like structure after 96 h MA.
