An Fe–11Cr–19Ni alloy single crystal having an initial orientation close to K011l{511} was deformed in tension. The uniformly deformed portion ( i.e. matrix) of the crystal was rotated about a <110> axis in the counterclockwise direction as tensile deformation proceeded. The rotation suggests that not only the slip systems on the primary slip plane but also those on the critical slip plane were involved in the deformation. After annealing, the matrix almost completely recrystallized. Orientation relationships were found between the deformed matrix and the recrystallized grains. The majority of the recrystallized grains was related to the matrix orientation by rotation about <111> axes. Among such recrystallized grains, those rotated about the conjugate-slip plane normal and those rotated about the cross-slip plane normal outnumbered the others. The rotation occurred in the clockwise direction, opposite to the deformation-induced rotation of the matrix.
