摘要：

Phase transformations in high-temperature alloys of the Ni-Cr-Fe-Nb system were studied. An optimum combination of ductility and high-temperature strength was provided in the alloy system by homogeneous nucleation of ′- and ″-phases and subsequent stabilization of the structure due to the segregation of a small amount of -phase over grain boundaries. It was suggested that the heat treatment regimes for the alloys must be chosen in accordance with the mentioned structural features.
