| Abstract Scope |
Fusion based additive manufacturing (AM) processes offer unprecedented flexibility with the component design space. Furthermore, understanding and control of the thermomechanical and thermokinetic phenomena occurring during AM processing can lead to intriguing microstructural features that previously required highly specialized processing. This talk will present selected examples where AM processing is leveraged for designing microstructures for extreme environments often present during energy generation and storage. Subsequently, the phenomena governing texture evolution during AM and the prospects of grain boundary design (with AM) for enhancing the hydrogen attack and embrittlement resistance of austenitic stainless steels are discussed. The implications of process-induced microstructural heterogeneities for mechanical behavior of high temperature steels for nuclear applications are also discussed. Process control strategies that enable mitigation of such heterogeneities are highlighted. Overall, this talk aims to provide a perspective on AM as an enabler for addressing the materials-manufacturing challenges for next generation power plants. |
