Abstract
It is known that the properties of high-temperature nickel alloys depend considerably on the amount of γ'-phase, which is determined, first of all, by the aging, regime. In order to evaluate the properties of these alloys it is expedient to establish the relation between the parameters of the aging regime and the amount of γ'-phase or, which is even more important, between the aging parameters and the mechanical properties. The present paper concerns high-temperature nickel alloys KhN56VMTYu and KhN77TYuR, which are used to establish the relations between the amount of γ'-phase, the hardness, and its increment due to aging and the aging temperature.
