| Abstract Scope |
Concentrated Solar Power (CSP) systems rely on materials that can withstand extreme thermal and mechanical stress. Haynes 282 (H282), a nickel-based superalloy, is known for its excellent high-temperature performance in conventional manufacturing, but its behavior when produced via Laser Powder Bed Fusion (LPBF) and welded counterparts remains underexplored. This study investigates the creep rupture behavior of LPBF-fabricated H282 and its welded counterparts to support CSP applications. Specimens were printed in vertical and horizontal orientations, then machine following the ASTM E139 standard geometry with some joined to wrought H282 by welding. All underwent a modified heat treatment and were tested at 760 °C and 800 °C under 350 MPa. Larson-Miller Parameter analysis revealed LPBF and welded specimens performed comparably to wrought H282. These results demonstrate that LPBF-fabricated and welded H282 retain creep resistance, supporting their integration into high-temperature CSP systems and promoting additive manufacturing in renewable energy technologies. |
