Aging Precipitation and Recrystallization Behavior After Aging at 750°C only the precipitation occurs and the precipitates consist of phase and M 2 N phase. Aging at 800°C precipitation occurs prior to recrystallization. Precipitation of large numbers of the second phase particles at the grain boundary hinders the formation of recrystallization nucleus.

Influences of Aging Precipitation on Corrosion Resistance Influences of aging precipitation of Cr2N and Chi () phases on the resistance to pitting corrosion and intergranular corrosion of 18Cr-18Mn-2Mo-0.77N high nitrogen steel (HNS) as a type of fundamental and structural materials were investigated using scanning electron microscopy (SEM), X-ray diffraction (XRD) pattern and electrochemical methods.
The precipitation behavior under neutron irradiation is generally consistent with near equilibrium thermodynamic with radiation-accelerated diffusion, including increasing number density with increasing Cr content and decreasing temperature, as well as heterogeneous nucleation on dislocations for lower Cr compositions and higher
Kinetics of Cr 2 N Precipitation and Its Effect on Pitting Sep 11, 2020 · In the present work, hot-rolled nickel-free high-nitrogen austenitic stainless steels (HNSS) were solution annealed and aged at 700, 800 and 900 °C for 14 h. Precipitation behavior of Cr2N at the grain boundaries (GB) of HNSS was studied using TC-PRISMA simulation and TEM analysis. Pitting corrosion behavior of HNSS at solution annealed and aged conditions were studied using cyclic
Precipitation Behavior of the Topologically Close-Packed Abstract. The precipitation behaviors of the topologically close-packed (TCP) phases in the bicrystal DD5 superalloy have been investigated. The results showed that the  crystallographic orientations are consistent with that of adjacent grains; however, the direction of the needle-like TCP phases is not consistent with that of the phase channels.
