A Neutron Diffraction Study of Texture Evolution under Deformation in a Hot Rolled TWIP Steel

Hot rolled TWIP steel was characterized using neutron diffraction methods. Texture was measured as a function of plate orientation and compressive deformation. It was found that the final texture after 10% uniaxial compressive deformation was the same irrespective of the orientation of the sample. In situ tests were carried out to obtain continuous data on twinning activity as a function of deformation. The intensity changes corresponding to twin activity were linear with strain during tensile deformation.
