Abstract

Abstract

Kinetic Process of zigzag grain boundary formation (ZGBF) in wrought nickel-base superalloys has been investigated.It was shown that the major phase of ZGBF is depended on the nature of alloys and parameters of heat treatment (temperature, cooling rate and so on), when two phases(γ', M₆C or M₂₃C₆) are coexisted at grain boundary.Two models are presented in this paper:one is used in ZGBF with two phases, the other is used to describe migration of (a segment) grain boundary.
