N2 - Multicomponent Ni-base alloys exhibit good mechanical properties even at elevated temperatures and they are widely used for industrial production of exertion-resistive parts of engines. These properties are mainly determined by the coexistence of a disordered gamma matrix with a face centred cubic lattice and cuboidal domains of its ordered gamma' structure. Therefore it is useful to study phase equilibria in Ni-base systems, namely in the regions involving both mentioned phases. One from the conclusions of our recent work on Ni-Al-Cr-W system was a necessity of modification of selected thermodynamic parameters for the ternary Ni-Al-W subsystem in order to achieve a better agreement of our experimental observations with theoretical modelling. This work involves, therefore, new measurements of microstructure on selected samples of the Ni-Al-W system at various temperatures and the comparison of the results with existing literature data confirming our conclusions on higher order system investigated before.
