Abstract
In this paper we introduce a new method to measure diffraction elastic constants of gamma double prime phase in Ni-base superalloys using in-situ neutron diffraction. During aging heat treatment of the alloys, stress is applied so that gamma double prime variants can be selected, which facilitates accurate fitting of the diffraction peaks. Then the Miller Indices reflections from different gamma double prime variants can be used to separate the overlapping gamma and gamma double prime diffraction peaks. The measured values agree with the elastic constants calculated using Kroner and Reuss models.
