Paper Title:
Effects of Mn on the Precipitation Behaviors in High-Nitrogen Austenitic Stainless Steels
  Abstract

Precipitation behaviors of Fe-18Cr-12Mn-0.48N and Fe-18Cr-18Mn-0.43N high-nitrogen austenitic stainless steels isothermally aged at 800°C were investigated by using optical microscopy (OM), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The results show that precipitation both display discontinuous cellular way and the major precipitates are both M2N phases accompanied by scattered M23C6 phases at grain boundary in the experimental steels. Increment of Mn content can not change the precipitation way and precipitation type. Increment of Mn content makes M2N precipitates obviously increase and increment of Mn and C contents makes M23C6 precipitates increase.
