Microstructural characterization of Y2O3 ODS-Fe-Cr model alloys

Abstract:

Two Fe-12 wt% Cr alloys, one containing 0.4 wt% Y2O3 and the other Y2O3-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 <...
