Paper Title:
Precipitation in Aged N-Containing Austenitic Stainless Steels
  Abstract

Three types of austenitic stainless steels JK2, JJ1 and JN1 were isothermally aged at temperatures from 873 to 1173 K for 10 to 1000 minutes in order to study the microstructural evolution. In general, the kinetics of precipitation for JN1 steel was faster than that of JJ1 steel, because of its higher interstitial solute content. The TTP diagrams showed that the intergranular precipitation of M23C6 and M2N preceded to the intragranular precipitation of M2N and M2N and η phase in JN1 and JJ1 steels, respectively.
