| Abstract |
Parameters needed in model calculations of the α/γ phase equilibrium in Fe-C alloys are calculated by using new Monte Carlo procedures. The parameters include the carbon-carbon interaction energies and standard carbon potentials in the αand γ phases and the relative lattice stability of pure bcc and fcc Fe. Accurate values of the model parameters are determined by a comprehensive analysis of the existing experimental carbon activity data in both the αand γ phases and by utilizing the Fe-C phase diagram. The parameters determined in the present work together with the new Monte Carlo procedures will surely provide more confidence in the low temperature extrapolation of the metastable α/γ phase equilibrium. |
