The reduction of freckle defect in the single-crystal blade root by controlling local cooling conditions was investigated. Application of the IRBs technique increased the temperature gradient from about 10 to 21 K/cm, thus reducing PDAS in the root compared to the standard Bridgman process. Refinement of the microstructure and reduction of the curvature of the liquidus isotherm resulted in mitigation or elimination of freckle in the area near the root edge.
