Abstract [en]

In the current study, the phase equilibria between fee, graphite and M7C3 (M = Cr,Co) have been studied at 1373 degrees K, 1423 degrees K, and 1473 degrees K. The solubility of Co in the M7C3 phase and the solubility of Cr and C in the fee phase have been determined by the high-temperature equilibration and quenching technique. Appropriate mixtures of Cr7C3 + Co or Cr7C3 + Co + C were equilibrated and subsequently quenched in liquid nitrogen. The quenched samples were characterized by X-ray diffraction and by metallographic examination. The studies were carried out on the samples to determine the homogeneity of the sample as well as the phases and their composition. From the results, the compositional regions of the three-phase triangle M7C3 + fee + graphite could be accurately determined. The results show that the Co solubility in the Cr7C3 in the experimental temperature interval is higher than previous investigations performed at higher temperatures.
