| Abstract Scope |
Advanced manufacturing techniques such as laser powder bed fusion, and diffusion bonding have enabled manufacturing of complex components such as compact heat exchangers, required for efficient power cycles such as sCO2 Brayton cycle in advanced nuclear reactors. Understanding how local microstructural defects introduced by these processes affect component performance is critical to accelerating their deployment. In this talk, we will present our work on modeling presence of secondary phase particles in a diffusion bonded microstructure using a crystal plasticity finite element model. The secondary phase particles may contribute to heterogeneous hardening behavior in the microstructure and act as potential sites for stress concentration and cavity nucleation – resulting in reduced creep ductility. The insights from this work can be used to change the processing parameters to enhance efficacy of the bonding process and thus improve the component performance. |
