Abstract Scope |
In recent years a number of groups have demonstrated the feasibility of printing Ni-based superalloy single crystals via electron beam melting (EBM) AM. In all cases the crystallographic orientation of the single crystal is deterministic with a precise secondary orientation preference. This control offers the possibility of producing components with desired orientation without the need for seed crystals. Optimizing such systems requires detailed knowledge of the deformation behavior of these single crystals. In this work we present properties of these single crystals produced via EBM AM. Mechanical tests are performed at various orientations to capture the crystal-scale behavior of the material. We demonstrate that the behavior coincides with established crystal plasticity theory. |
