Orientation correlations in primary recrystallized Fe-50%Ni

The correlations between orientations of neighboring grains have been inves tigated in a Fe-50%Ni alloy after primary recrystallization and normal grai n growth. Boundary misorientations have been determined by systematic measu rement of individual grain orientations by Electron Back-Scattered Diffract ion (EBSD). It is shown that the recrystallization process in Fe-50%Ni give s rise to noticeable orientation correlations for Sigma3 " and low-angle or ientation relationships. Such correlations result mainly from the non-rando m spatial distribution of orientations and from the grain size dependence o n orientation developed in these alloys during recrystallization. In the pr esent alloy. the grain growth process leads to minor variations in the orie ntation correlations associated with low-angle misorientations and reduces considerably those related to Sigma3 " orientation relationships.
