Material anisotropy in additive manufactured nickel-based superalloy and its effect on macroscale behaviour
This experiment will investigate the relationship between microstructure and macro-scale mechanical properties of an additive-manufactured nickel-based superalloy. We will use SALSA to observe neutron scattering from single crystallites close to the crack tip in differently-oriented fracture specimens of additively-manufactured material. Digital image correlation will be used to track these crystallites as the specimens are loaded, and to measure total strain at the surface of the specimens. Using these measurements of elastic and total strain we will determine how the fracture process interacts with the inhomogeneous grain structure of this material.
