Abstract
Alloys with a different content of ′-forming elements have been studied. High-temperature ductility of heat-resistant nickel alloys with a different content of ′-forming elements after heat treatment at a different cooling rate has been evaluated. It has been established that heat treatment allowing to control growth of the ′-phase is indicated only for alloys with a high degree of alloying.
Keywords: nickel alloys, ′-forming elements, heat treatment, cooling rate, high-temperature ductility, microstructure, dilatometer, phase transformations
