Assessing Dislocation Densities in the Gamma Prime Phase of a Superalloy from High Resolution Diffraction Peak Shape

Abstract:

The shape of the diffraction peaks of a single crystal superalloy measured by Three Crystal Diffractometry changes during a creep test. We show that these variations are directly linked to the strain and dislocation density within the γ’ phase.
