Precipitation in Aged N-Containing 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 Cr₂₃C₆ and Cr₂N preceeded to the intragranular precipitation of Cr₂N and h phase in JN1 and JJ1 steels, respectively.
