Abstract

 The general trends of grain structure development during friction stir welding (FSW) were studied. The microstructure evolution at relatively low welding temperatures was shown may be primarily governed by grain subdivision. At elevated temperatures, however, discontinuous recrystallization may play a key role. Inhomogeneous microstructure distribution was revealed in stir zone.
