This five-year, $641,328 National Science Foundation Project Grant supports research at the Colorado School of Mines to advance additive manufacturing of nickel-based superalloys for clean energy applications. Funded through NSF's Engineering program (CFDA 47.041), the award will develop a mechanistic understanding of how wire arc additive manufacturing processing conditions influence the microstructure and high-temperature mechanical properties of Haynes 282 superalloy. The research combines fabrication experiments, characterization, and computational modeling to investigate deposition parameter effects on as-built microstructure and morphology, as well as the potential of hot isostatic pressing to reduce defects while controlling grain size. It will evaluate how controlled microstructures influence tensile, fatigue, and creep performance at 800-900°C relevant to demanding power plant environments. Broader impacts include educational activities with a two-year welding program to develop automation curriculum shared nationwide to promote workforce diversity, agility, and energy security.
