【 摘 要 】

This study mainly observed the Cr₂N (chromium nitride) nucleation and growth in SAF 2507 duplex stainless steel. However, the investigation revealed that Cr₂N has a complex substructure separated into many regions. In SAF 2507 duplex stainless steel, Cr₂N nucleated at the dislocations and the precipitates were composed of many Cr₂N flakes gathered together when aged at 600 °C.
