Dr. Lingfeng He received an award from U.S. Nuclear Regulatory Commission (US NRC) as a part of FY2024 Research and Development Grant. Title of the proposal is “Microstructure-Based Strength Prediction of Additively Manufactured 316H Stainless Steel After Post-Build Processing“. The awarded R&D funding is $0.5M. The objectives of this proposal are:
- To develop a microstructure-based physics model that predicts the mechanical strength of laser powder bed fusion (LPBF) manufactured 316H stainless steel (SS) following post-build processing.
- To use advanced characterization and simulation techniques to analyze phase structure, composition, precipitates, defect characteristics, and mechanical properties of LPBF 316H SS.
- To implement the developed models in the LPBF 316H SS performance code to assess the effects of post-build treatments, addressing key knowledge gaps for the Nuclear Regulatory Commission (NRC) in qualifying LPBF 316H SS for advanced non-light water reactors (ANLWRs).
The collaborators for this project are:
- Wen Jiang, NC State University
- Korukonda Murty, NC State University
- Ram Mohan, North Carolina A&T State University
MIX group would like to thank US NRC for this funding support. Also, heartiest congratulations to Dr. Lingfeng and the collaborators for this award!
