Abstract: The present work is to study the effect of phosphorus on the annealing texture of a low carbon steel at different cold rolling and annealing condition by means of pole-figure,inverse-pole figure and orientation distribution function(ODF)method.The microstructure and distribu- tion of phosphorus in steel sheet are studied by means of metallography,scanning electron mi- croscope(SEM)and electron probe microanalysis(EPMA).The results show that phos- phorus promotes the formation of the fiber texture of〈011〉parallel to the rolling direc- tion and〈111〉normal to the sheet surface.The texture was found to be affected mainly by preannealing temperatures,promoted at 390 or 590℃,and retarded at 490℃.At the preannealing temperature promoting the formation of texture,phosphorus segregation to the interior of grains was observed.It seems that the formation of the fiber texture may be associ- ated with the segregation of phosphorus.

Key words: low carbon steel, segregation of phosphorus, texture
