Cover Story: Process parameter selection in the additive manufacturing of metallic structures is vital, especially in nickel-based superalloys, wherein the multiple stages of melting and solidification during fabrication result in complex microstructures composed of grains of numerous sizes, shapes, and orientations. Qualification standards to ensure that products meet specific criteria are dependent on process parameter selection. There exists an urgent need for nondestructive qualifications to determine these process parameters. Herein, we explore different ultrasonic NDE parameters that could potentially be used as nondestructive qualification parameters for laser-DED IN718 parts. These parameters quantify the anisotropy, microstructural heterogeneity, average cluster size, and grain or cluster size contribution to ultrasonic attenuation. View this paper
