Abstract
Effects of cold rolling with grooved rolls and following flattening on both the cold rolling texture and the primary recrystallization texture of extra low carbon Al-killed steel sheets have been studied by crystallite orientation distribution function (ODF) analysis.Consequently, it was clarified that the preferred orientation of the sheet subjected to the groove-rolling followed by flattening shifted from {112}<111> to {100}<011>. With change in the cold rolling texture, the primary recrystallization texture of the groove-rolled sheet was composed of lower {111}<110> and higher {100}<0vw> as compared with that of the conventionally flat rolled one. The results suggest that the lattice rotation around <110> axis which is parallel to the transverse direction is accelerated by the groove-rolling.
