Abstract

Phase coexistence in the Fe-C-Si-Mn-Cr system, as the base system of a large number of low alloy steels, has been studied experimentally and theoretically. The vertical section of the phase diagram of the Fe-C-2Si-2Mn-1Cr system near the eutectoid point (700-900 degrees C; 0.14-0.80 wt.-%C) and the chemical composition of the phases present were determined by means of scanning electron microscopy and energy dispersive X-ray analysis. Thermodynamic calculations of the Fe-C-Si-Mn-Cr system equilibria, based on the Hillelt-Staffansson model, for low contents of silicon, manganese, and chromium were performed. These calculations gave results very close to both the experimentally determined phase boundaries and the composition of phases. A wide eutectoid zone (about 50 K) was found to exist in the system, for all carbon contents studied.
