Abstract

V originále

Several alloys of Ni-Al-Cr-Co system with constant Ni content of 70 at.% were studied at 900 and 1000 C by means of analytical electron microscopy, with respect to the gamma and gamma'; phase field existence. The results showed good agreement with calculated data obtained by means of the software Thermo-Calc. In order to obtain the better agreement of theory with experiment, an optimization of some thermodynamic parameters in used model was performed.
