This work summarizes the results of microstructural design and alloy development in the Path A Prime-Candidate Alloy (PCA). The basis for the microstructural design, basically, is the well-established MC-helium trapping mechanism and its correlation with improved swelling and embrittlement resistance in HFIR-irradiated 316 + Ti. A range of preirradiation microstructures were designed with variable combinations of matrix and grain-boundary precipitation prior to actual investigation of the PCA.
