Abstract Scope Oxide dispersion strengthened (ODS) ferritic alloys are attractive materials for high dose applications in nuclear power plants due to resistance to void swelling and embrittlement. Gas Atomization Reaction Synthesis (GARS) powder processing may reduce current high-cost, lengthy mechanical alloying methods for particulate-processed ferritic ODS alloys. Pairing GARS pre-alloyed (including Y) precursor powders with high energy cold spray (CS) deposition could permit final shape forming of ODS steels, particularly for potential increased dislocation densities and oxide nucleation sites that can increase strength. Next stage development of GARS ODS alloy design produced a batch of powder that includes both Al and Zr due to capability for alumina scale formation, along with nano-oxide dispersoids that are stable up to 1,000C and desirable neutron cross section for high dose structural applications, respectively. Characterization of the as-atomized powder and initial CS results will be compared to literature reports of the desired alloying element concentrations.
