Crystallography of grain boundary (GB) bcc-precipitates formed in a lightly pre-deformed fee-matrix phase was examined in a Ni-43Cr alloy by EBSD with emphasis on a misorientation from the Kurdjumov-Sachs orientation relationship. The misorientation of GB bcc-precipitates became somewhat larger when the matrix phase was lightly pre-deformed. The GB bcc-precipitates were preferentially formed at the intersection of geometrically necessary dislocation boundaries (GNB) with grain boundaries. In contrast, the pre-deformation did not influence the misorientation of intragranular bcc-precipitates. The preferential precipitation and the increased misorientation at the GNB-GB intersection were discussed.
