Microstructural characterization of PCA-type splat-quenched foils of austenitic stainless steels irradiated in the HFIR to 14 dpa, 750 appm He

Description

The results of microstructural characterization of rapidly-solidified (RS) foils irradiated in the High Flux Isotope Reactor (HFIR) to 14 dpa/750 appm He at 773 K and 873 K are reported. RS foils with nominal Ti and C concentration of 1, 3 and 5 times the amount contained in prime candidate (PCA) stainless steels (0.32 Ti, 0.046 C) were prepared and three thermomechanical treatment were employed to obtain variations in the pre-irradiation microstructures. Quantitative electron microscopy results for void swelling, dislocation structure, radiation-induced phase transitions and segregation of defects/He to interphase boundaries are discussed. Higher swelling was found at 773 K compared to 873 K and in annealed materials, consistent with a model for swelling suppression based on thermal and recoil re-solution precipitation effects. Voids were not found at particle/matrix interfaces. Under the conditions of this experiment, RS processing and increased Ti and C did not significantly alter the swelling behavior
