Abstract
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.
