Abstract Scope |
This study investigates the mechanical properties of diffusion-bonded 316H and A617 specimens in high-temperature environments, crucial for advanced nuclear applications such as compact heat exchangers. We analyze bond strengths and failure mechanisms under various mechanical loads at elevated temperatures. Our methodology integrates advanced testing techniques, including tensile and creep tests with Digital Image Correlation (DIC), to evaluate material response to mechanical stress and time-dependent deformation. Electron Backscatter Diffraction (EBSD) and Transmission Electron Microscopy (TEM) analyses provide insights into microstructural characteristics, grain orientation, and potential segregation near bonds. Additionally, strain hardening analysis and dye penetrant tests are conducted to assess mechanical behavior and identify potential defects. This comprehensive approach enhances our understanding of diffusion-bonded 316H and A617 performance in demanding operational environments, informing the design and optimization of high-temperature applications across multiple advanced energy sectors. |
