It has been shown by many research workers that a good drawability or a high strain ratio value can be attained in properly processed aluminum killed steel sheets and the higher density of near {111}<112> or {111}<110> component in the recrystallization textures is responsible for the higher strain ratio values of the sheets. The authors have recently obtained high densities of the near {111}<112> and {111}<110> components in the recrystallization texture of a rimmed steel sheet. The massive transformation structure was obtained in the hot-strip of a rimmed steel (C=0.06 wt%) by quenching from 920℃. After ageing at 200°∿250℃ for 3 hr, the strip was cold-rolled 70% and finally annealed at 700℃ or 800℃ in wet hydrogen or argon atmosphere. The (200) pole figure of the finally annealed sheet showed strong intensity maxima around the poles corresponding to the near {111}<112> or {554}<225> and {111}<110> orientations. The pole density of {222} parallel to the sheet plane divided by that of a random specimen was 6.7∿7.1. The results are discussed in relation to the inhibition of the recrystallization process by finely dispersed Fe_3C particles.
