Numerical simulation of Cr2N age-precipitation in high nitrogen stainless steels

At the temperature raging from 700 to 950 deg C, the Cr2N age-precipitation in high nitrogen austenitic stainless steels Fe24Mn18Cr3Ni0.62N was investigated in this paper. A qualitative mathematical model of Cr2N age-precipitation, ln ts = f (Me, l/T), was established based on the thermodynamics and...

Zusammenfassung:At the temperature raging from 700 to 950 deg C, the Cr2N age-precipitation in high nitrogen austenitic stainless steels Fe24Mn18Cr3Ni0.62N was investigated in this paper. A qualitative mathematical model of Cr2N age-precipitation, ln ts = f (Me, l/T), was established based on the thermodynamics and kinetics and phase transformation theories. Satisfactory results were obtained by means of the test of artificial neural network. This mathematical model can be applied to the calculation design and predication of Cr2N age-precipitation in high nitrogen stainless steels.
