Varga, E. Kuzmann, M. Káldor, A. Vértes] Mössbauer spectroscopy was used in order to get information about the anomalous austenite formation1 taking place between 450-600 °C in steel containing 12%Cr and 4%Ni. Even below the equilibrium transition temperature (640 °C) of α→γ transformation a monotonic increase of the relative spectral area of the line belonging to austenite was observed in the Mössbauer spectra of the steel isothermally aged at 550 °C with increasing ageing time. At the same time, the Cr content of the ferrite phase decreases. Time dependence of the quantity of austenite formed during the isothermal ageing follows the Avrami-kinetics with an exponent n=0.3.
