This experiment will investigate the relationship between microstructure and macro-scale mechanical properties of an additive manufactured nickel-based superalloy. We will use ENGIN-X to observe neutron scattering from crystallites close to the crack tip in differently-oriented fracture specimens of additively-manufactured material. Strain measurements using neutron diffraction will be used to track changes in elastic strain within the crystallites as the specimens are loaded. Crack propagation will be observed simultaneously using the compliance of periodic small unloads. Using these measurements we will determine how the fracture process interacts with the inhomogeneous grain structure of this material.
