Microstructure Properties of EP-450 ODS Steel Manufactured by Highvoltage Discharge Compaction Technique

Oxide dispersion strengthened 13Cr-2Mo steel powder was successfully consolidated using high voltage discharge compaction to near theoretical density. Such rapid process in combination with high transmitted energy allows obtaining high density of the compacts, saving initial structure with minimal grain growth. Heterogeneity of the structure may occur in the boundary layers of the sample due to thermal and electromagnetic effects but the choice of optimal parameters of consolidation allows obtaining samples of acceptable quality.
