: Detailing the laser parameters used to achieve high densification levels.

: Components in hydrogen-sensitive LREs are prone to hydrogen environment embrittlement. HR-2 was formulated as a promising solution for hardware produced via Laser Powder Bed Fusion (L-PBF) , a type of 3D printing that allows for complex geometries. Methodology : hr2.zip

: NASA HR-2 is a mature and viable candidate for critical aerospace hardware, successfully combining printability with robust mechanical performance in hydrogen-rich atmospheres. : Detailing the laser parameters used to achieve

: Tensile testing conducted in pressurized gaseous hydrogen (GH2) at up to 5 ksi. Results & Discussion : Methodology : : NASA HR-2 is a mature

: Data confirms that high-pressure hydrogen has minimal influence on the alloy’s fracture elongation (34–36%), demonstrating superior resistance to embrittlement compared to standard alloys.

: Standard procedures used to optimize the microstructure for tensile strength.
