Mechanism and kinetics of coagulation of γ′-phase in nickel alloys at temperatures of hot plastic deformationin nickel alloys at temperatures of hot plastic deformation
1997
It is known that hot plastic deformation of hard-to-deform complexly alloyed heat-resistant nickel alloys is easier to conduct at temperatures of the double-phase region than at those of the single-phase region. In heating such alloys before deformation and in the process of deformation cooling of them the amount of strengthening γ′-phase and its sizes and distribution change, which exerts a substantial effect on their susceptibility to hot plastic deformation in the double-phase range. For this reason, knowledge of the laws of variation of the amount, dispersity, and distribution of the strengthening γ′-phase in heating to the deformation temperature is very important, because it makes it possible to control these processes.
