Verifying and improving self-consistent elasto-plastic models for two-phase coherent materials

DOI

In this experiment, we aim to clarify how different deformation mechanisms are best incorporated in a so-called elasto-plastic self-consistent model. The model is developed to predict the behaviour of materials with specific orientation relationships between the crystals in the two different phases. We will perform in-situ neutron scattering measurements during tensile testing of a Ni-base superalloy with microstructures designed to enhance or suppress lattice co-rotation, a local boundary condition resulting from the orientation relationship between the phases. The results will be used to systematically assess the effect of different assumptions made in the model, and to develop approaches to describe different deformation mechanisms in the simulations.
