Description

It has been shown by many research workers that a good drawability or a high strain ratio value can beattained 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 thesheets. The authors have recently obtained high densities of the near {111}‹112› and {111}‹110› componentsin the recrystallization texture of a rimmed steel sheet.<BR>The massive transformation structure was obtained in the hot-strip of a rimmed steel (C=0.06wt%) byquenching from 920°C. After ageing at 200°V-250°C for 3 hr, the strip was cold-rolled 70% and finallyannealed at 700°C or 800°C in wet hydrogen or argon atmosphere. The (200) pole figure of the finallyannealed 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 bythat of a random specimen was 6.7-7.1.<BR>The results are discussed in relation to the inhibition of the recrystallization process by finely dispersed Fe3C particles.
