In-situ neutron diffraction study: High temperature anisotropic deformation mechanism of Ni-based superalloy built by additive manufacturing

Abstract: The typical texture and columnar grain structure are suspected to be the reason for the anisotropic mechanical properties of materials built by additive manufacturing (AM). The proposed in-situ tensile tests at 700?C are beneficial for the fundamental understanding of anisotropic deformation mechanism, and also the different behavior at slow strain rate. The study material is a solid solution strengthened alloy, Hastelloy X, built by laser powder bed fusion, which has no gamma prime precipitation and is relatively easy to obtain crack-free components. Hence, the work could mainly focus on the influence of texture and grain structure. Combined with the preliminary work on the microstructure and texture study of deformed samples, a deformation mechanism model for Ni-based superalloy could be established. The study could be highly beneficial for building up robust AM applications.
