| Abstract Scope |
Additive manufacturing (AM) provides a tremendous opportunity to synergistically couple materials, design, and manufacturing strategies. To make AM a substantial manufacturing strategy, one must incorporate its unique attributes of optimizing alloy composition, design and manufacturing modalities to fit site-specific performance needs, by tailoring metal-metal or metal-ceramic compositional transitions. The current effort explores alloys that are being used at high temperatures and extreme environments – specifically to investigate phase transformations and deformation mechanisms in additively manufactured Ni-base superalloys (IN718) graded to Nb-based refractory alloys (C103). The study will enable synergistic coupling of experimental and modeling tools to design pathways for compositional gradation and understand the thermal response on phase/stress evolution of additive builds in a spatio-temporal manner. This concept is really material agnostic, and can be beneficial for fabricating parts with targeted site-specific properties for a wide range of applications in extreme environments in aviation, space, and energy sectors. |
