  The excellent mechanical performance of oxide dispersion strengthened(ODS)steels is attributed to the highly dispersed and extremely stable oxide particles with diameters of a few nanometers.Studies were made to determine the microstructure and tensile properties of a 14Cr ODS ferritic steel with the nominal composition of Fe–14Cr–2W–0.3Ti–0.2V–0.07Ta–0.3Y2O3 produced by HIP in this work.The microstructure investigations revealed numerous nanoparticles with the average size of 5 nm located at the grain boundaries and inside the grains.And the average grain size was founded to be smaller than previous reports.Results of the tensile test at room temperature proved the studied steel is more ductile than the other similar ODS ferritic steels of literature,which is due to the addition of vanadium and tantalum.
