Abstract
method for phase analysis of three-component alloys is proposed. It is based on a pair interaction model and an experimental determination of the sign of pair chemical interaction energy and includes an electron-microscopic investigation of microstructures above and below the ordering–separation phase transition temperature for each diffusion couple. This method is used to study an Ni50Co25Mo25 alloy. The phases that precipitate in this alloy over the entire heating temperature range, including the liquid state, are detected.
