Abstract

The effects of Cu addition on the microstructure and localized corrosion of hyper duplex stainless steels aged at 748K were investigated using TEM analysis and electrochemical test. The addition of Cu to the base alloy facilitated the precipitation of a Cr-enriched α′A-phase due to an increase in the Cr activity, thereby reducing the localized corrosion resistance. The localized corrosion was initiated at the Cr-depleted regions around the Cr-enriched α′-phase.
