Oxide-dispersion strengthened (ODS) ferritic steels are extraordinary candidates for use in some extreme conditions (as for Gen IV reactors) for this purpose it is necessary to have an excellent creep behavior. The nature, size, locations of precipitates determine the response of the steel. Alloying elements, as Ti, Al, Y allow the formation of nano-precipitates which will limit the movement of dislocations, will promote the hardening of material and therefore enhance creep behavior. Seeking for precipitates refinement, addition of Zr applies for the formation of more stable oxides (Y-Zr-O) instead of Y-Al-O. This work compere the effect of a Zr addition with those processed free from it. The ODS ferritic steel was produce starting from a prealloyed grade (Fe-14Cr-3W-5Al) by mechanical alloying with the addition of 0.6Zr+0.4Ti+0.25Y2O3. TEM will provide details of the grain structure, precipitates and dislocations location developed through MA and after fully-dense consolidation.
