Abstract

Textural changes occurring in deformed BCC single crystals of (001)[110], (001)[100], and (110)[001] orientations have been studied by simulation of plastic deformation. It was shown that a correlation between microstructure and texture must be taken into account to interpret existing experimental data. Rolling of (001)[100] single crystals give rise to two microstructure types that correspond to different texture components, {001} <100> and {001}<230>, with the first component accommodating a transition in orientations between two symmetrical positions of second component. Suggestion that such a behaviour must be widely observed in other unstable orientations has been put forward. For example, if a (110)[001]-oriented crystal does not undergo mechanical twinning and its rolling texture can be presented as a sum of two components {112}<111> and {110}<001>, we must also expect the presence of two corresponding structure types. Disclination mechanisms of formation of the transition structure textural components have been considered.
