Abstract

In super duplex stainless steel, austenite-ferrite boundaries are preferential sites for the precipitation of chromium nitride (Cr₂N) during heat treatment. In this study, we observed a large number of Cr₂N rods were continuously lined up on a thin lamella of M₂₃C₆ of 20 nm width along an austenite-ferrite boundary. This observation indicates that M₂₃C₆ carbides at the boundary play a significant role in promoting the formation of Cr₂N rods.
