- Abstract
- The influence of deformation localization during tensile deformation on the development of crystallographic texture in twinning-induced plasticity (TWIP) steel is reported. Whereas Al-added TWIP steel deforms homogeneously before the critical strain of onset of serrations, plastic deformation in Al-free TWIP steel occurs by propagation of isolated Portevin-Le Chatelier bands from the early stage of plastic deformation. The crystallographic texture evolution of both steels is, however, very similar. Deformation leads to the development of a Cu-type texture characterized by the strengthening of the rotated Brass component rather than the pure Brass component. (C) 2012 Acta Materialia Inc.
