Abstract The present work is to study the effect of phosphorus on the anneal-ing texture of a low carbon steel at different cold rolling and annealing conditionby means of pole-figure, inverse-pole figure and orientation distribution function(ODF) method. The microstructure and distribution of phosphorus in steel sheetare studied by means of metallography, scanning electron microscope (SEM) andelectron probe microanalysis (EPMA). The results show that phosphorus promotethe formation of the fiber texture of <001> parallel to the rolling direction and<111> normal to the sheet surface. The texture was found to be affected mainly bypreannealing temperatures, promoted at 390℃ or 590℃, and retarded at 490℃. Atthe preannealing temperature promoting the formation of texture, phosphorus segre-gation to the interior of grains is observed. It seems that the formation of the fi-ber texture may be associated with the segregation of phosphorus.
