| Popis: | The phase equilibria in the Ni-rich part of the Ce–Ni binary system were re-determined using DTA, metallography and SEM/EDX. CeNi5+x presents a Ni solubility up to x = 0.53 at 1073K. The melting point of CeNi5 is 1608±5K and the CeNi5+x –Ni eutectic has been observed at 1477±5K and x(Ni) = 0.91. The enthalpy of formation of stoichiometric CeNi5 has been measured by drop dissolution calorimetry in liquid aluminium and a value of ΔfH = −29.1±2.2kJ/moles of atoms was derived. Based on this new experimental data and literature values, a complete thermodynamic modelling of the Ce–Ni diagram was performed. |
