Enabling Production of Hydrogen-Compatible Metal-Base Structural Material for High-Temperature Use through Wire-DED Additive Manufacturing

Long-term durability of metal-base structural components under high-temperature hydrogen-containing environments is one of the non-negligible subjects to establish the hydrogen-base society, especially for energy production sectors. The study will aggressively raise the bottom line of the materials performance required under hydrogen exposure, by considering survival of structural components in such harsh environments through newly proposed alloy design strategy. By combining additive manufacturing (AM) technology with wire-direct energy deposition (DED), a rapid deployment of structural components is highly expected.
