NSUF 25-5247: Acoustoplasticity induced microstructural modification to mitigate stress corrosion cracking in stainless steel 316L

This work will study the irradiation assisted stress corrosion cracking performance of acoustoplastically treated samples. Acoustoplasticity (AcP) is the use of high intensity acoustic waves to create localized plastic deformation. AcP has been show to produce fine grained microstructure, induce a complex stress state and result in texture. This project will explore the potential of AcP as a treatment method to mitigate IASCC and protect surfaces. We anticipate a project period of less than 9 months. The ability to create IASCC resistant structures, potentially repair IASCC damage and tailor/control microstructure are the most significant outcomes expected from this experiment. If successful, this method will be economical, can operate in room temperature and be used in the field to make IASCC resistant structures. This will be a significant push in the state-of-the-art of methods to mitigate IASCC.
