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

: NASA HR-2 is a specialized superalloy developed to withstand the extreme conditions of liquid rocket engines (LREs). This paper explores its mechanical properties, including high yield stress (~95 ksi) and exceptional ductility in high-pressure hydrogen environments. 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. : Standard procedures used to optimize the microstructure

: 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 : : NASA HR-2 is a mature and viable

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