Description In order to gain more experimental information on the Ni-Al-W system with the aim to obtain a final reassessment of this system and its consequent utilization for new thermodynamic description of the Ni-Al-Cr-W higher order one, additional experimental investigation at 1000 and 1100C was realized. The data were used for optimization of thermodynamic parameters using module PARROT in software package ThermoCalc. As the source database of thermodynamic data, commercial database for Ni-based alloys was applied.
