Resumen:
The Mössbauer signal of Fe–C austenite is difficult to interpret because different Fe–C configurations give rise to different hyperfine interactions. Two competing models for the distribution of carbon atoms in the fcc austenite lattice have been proposed to account for Mössbauer spectra. Both models assume a repulsive C–C interaction of different magnitude and different Fe–C configurations. From the Mössbauer spectra, the abundance of the different iron sites could be determined. That abundance may also be calculated with Monte Carlo simulations. In this work, using the two controversial models, we compare the relative fractions of the Fe–C configurations obtained from Mössbauer spectra of vermicular austempered cast iron with Monte Carlo simulation.
