| Abstract Scope |
Advanced nuclear systems are currently being developed as part of a technology roadmap centered on the energy conversion system as well as the facilities associated with the fuel cycle.
Compact heat exchangers (CHX) are considered highly efficient due to their high thermal efficiencies, minimal pressure reductions, and moderate to high design pressure capacities.
Failure analysis will be performed to establish and validate acceptance criteria as intended for the service life to ensure that the mechanical properties of the diffusion-bonded material at elevated temperatures are comparable to those of the wrought product.
In the research, the mechanical characteristics of bond samples are analyzed using the combined results of two techniques, DIC and EBSD.
The objective is to evaluate the effect of the diffusion bond on mechanical properties, such as stress-strain state on the diffusion bond and bonding strength, by analyzing the microstructure and deformation of grains near the diffusion bond. |
