| Description | The Ni-Al-W system was studied experimentally and theoretically at temperatures 1173, 1273 and 1373 K in region of gamma, gamma' and alpha phase existence and new experimental results were obtained. Thermodynamic calculations were done using software package Thermo-Calc. The experimental data were confronted with calculated results obtained using commercial database for Ni-based superalloys. The thermodynamic description was optimized and very good agreement of experimental information with theory was obtained. |
