| Description | Several experimental alloys were prepared and new information on the gamma and gamma' phase equilibrium has been obtained. Phase compositions and phase ratios for the temperature 900 and 1000 C yielded the possibility to compare theoretically calculated sections of phase diagrams with experimentally determined ones. Very good agreement has been obtained for the Ni-Al-Cr-Co system, where additional thermodynamic parameters were derived. For the Ni-Al-Cr-W system, only a partial prediction from thermodynamic data on lower order systems could be obtained. |
