Microstructural and mechanical characterization of ODS alloy produced by surface oxidation method

    Research output: Chapter in Book/Report/Conference proceedingConference article in proceedingsScientificpeer-review


    Oxide dispersion strengthened steel was manufactured utilizing gas atomization processing from alloyed Cr-steel powder. Investigated material represents results on utilization of the processing route, which does not require mechanical alloying step, as high oxygen affinity elements are used. The surface oxidation of the powder particles and HIP consolidation of this precursor powder were investigated. The effect of hot working to the microstructure and mechanical properties were studied. High degree of hot working resulted in finer grain size than as-HIPed steel, without visible prior grain boundaries and with a uniform yttrium oxide dispersoids distribution. Results for small punch tests are also presented.
