High Nitrogen Austenitic Stainless Steel Precipitation During Isothermal Annealing

Maria Domankova, Katarína Bártová, Ivan Slatkovský, Peter Pinke

Abstract


The time-temperature-precipitation in high-nitrogen austenitic stainless steel was investigated using light optical microscopy, transmission electron microscopy, selected area diffraction and energy-dispersive X-ray spectroscopy. The isothermal precipitation kinetics curves and the corresponding precipitation activation energy were obtained. The diffusion activation energy of M2N precipitation is 129 kJ/mol. The results show that critical temperature for M2N precipitation is about 825°C with the corresponding incubation period 2.5 min.
