Abstract
Oxide dispersion strengthened steel can be manufactured
without mechanical alloying by gas atomization of
Cr-steel powder alloyed with high oxygen affinity element
like yttrium, titanium and hafnium, surface oxidation of
the powder particles, and HIP consolidation of this
precursor powder. In this presentation the results of the
gas atomisation of the 0.5Y-0.3Ti alloyed 9Cr ferritic
steel powder, surface oxidation of the powder, HIP
consolidation of the oxidised powder, and the
thermomechanical treatment of the HIPed material will be
presented. In the microstucture characterizing, OM, SEM
and TEM were used. The results indicate that ODS steel
can be produced by careful performing of the whole
process, from the alloying through the oxidation and
consolidation to the post-treatment. The oxygen content
and HIP conditions were suggested to be the most
significant parameters in the successful processing.
