Popis:	1. The program developed for the calculation of phase stability is able to predict the influence of composition on the formation of phase in complex cast metal alloys, based on phase analysis data and theoretical assumptions. The utility of the program was confirmed by direct experimental investigations. 2. Exceeding critical concentrations of titanium and aluminum (Ti+Al>13.27%) or chromium and tungsten (>19.5 and >3.5%, respectively) in complex nickel alloys results in the formation of σ-phase with deterioration of the useful properties.
