Microstructural characterization of YO ODS-Fe-Cr model alloys

Abstract:

Two Fe-12 wt% Cr alloys, one containing 0.4 wt% YO and the other YO-free, have been produced by mechanical alloying followed by hot isostatic pressing. These oxide dispersion strengthened and reference alloys were characterized both in the as-HIPed state and after tempering by transmission electron microscopy and atom-probe tomography. The as-HIPed alloys exhibited the characteristic microstructure of lath martensite and contained a high density of dislocations. Small voids with sizes <10 ...
