The recrystallization behaviour of shear bands induced in a cold-rolled (112) [111^^-] copper single crystal was investigated. The orientations of small recrystallized grains were determined by means of the electron chanelling pattern (ECP) and the Kossel pattern technique. At the early stage, recrystallization occured only within shear bands, however, the recrystallized grains did not grow into the matrix regions between shear bands. Most of grains grown in a shear band had the twin relationships of the first to the third order each other. At the later stage, recrystallization in the matrix region occured and the preferential growth of the grains having a 30° <111> relationship with the matrix texture was observed. These recrystallization behaviours can be expressed by assuming that the texture in well-developed shear bands is different from that in the matrix region.
