NSUF 16-853: Cavity Shrinkage in Fe21Cr32Ni under in situ Ion Irradiation
In-situ ion irradiations will be performed at the Intermediate Voltage Electron Microscope (IVEM) facility in order to study the dynamics of cavity growth and shrinkage in Fe21Cr32Ni, a simple model analogue to the commercial alloy 800H. Previous in-situ irradiation of electropolished thin foils have shown that cavities do not form over a wide range of temperatures, and pre-formed cavities shrink at 440°C in alloy 800H . Irradiation experiments will be performed over a range of temperatures and individual cavities will be followed to ascertain their behavior with irradiation. This data will then be used to inform the mechanisms of defect-cavity reactions under irradiation in this alloy. It is expected that this research will be performed within the next year (up to September 2017)
