In the last decade, metal additive manufacturing (AM) process has shown the potential to fabricate complex components of homogenous materials. Most of international research focuses on maturing AM to compete with traditional manufacturing processes including casting, forging and machining. None of the current efforts focuses on using the inherent site-specific building capabilities of AM. Recently, ORNL researchers have shown the proof of principle for manipulating the crystallographic texture (face-centered-cubic, FCC) in a homogeneous alloy (i.e. alloy 718). However, the generality of this scientific methodology for wide range of composition and phases has not been proven. Our overarching scientific question is the following: is it possible to disperse materials with different crystal structures (e.g. FCC, BCC and HCP) in precise geometric locations at different length scales (nm to mm) to induce tailored properties, while maintaining stability of these structures during long-term cyclic loading or thermal exposure? Current work will be shown.
