Demonstrates the impact of welding on Haynes 282 alloy’s integrity under creep conditions, suggesting its suitability for concentrated solar power systems.
This study investigates the creep rupture behavior of the additively manufactured Haynes 282 alloy (H282), which is fabricated using laser powder bed fusion (LPBF), and its welded counterparts. The alloy is evaluated for its suitability for high-temperature applications in concentrated solar power (CSP) systems. Using the Larson-Miller parameter (LMP) as a reference, the creep performance of the LPBF-fabricated H282 was found to be comparable to that of the conventionally manufactured alloy. Detailed analysis further revealed the influence of the build orientation on the creep response and the impact of welding on the material's integrity.
