ORIGIN OF RECRYSTALLIZATION TEXTURE EVOLUTION AND ACTIVE SLIP SYSTEMSIN COLD-ROLLED 3-PERCENT-SI-FE(100)[011] SINGLE-CRYSTAL

3%Si-Fe (100)[011] single crystal was investigated to analyze its text ure evolution during rolling and recrystallization. Cold rolled (100)[ 011] could be fully recrystallized by utilizing dynamic strain aging, and sharp recrystallized texture was obtained. Rolled texture maintain ed the initial orientation (100)[011] with TD rotational dispersion. T his dispersion is attributed to the action of two kinds of {112}[111] slip systems which have the largest Schmid factor. Recrystallized text ure is composed of eight orientations rotated about 30 degrees around eight (112) axes from the initial orientation (100)[011]. These rotati ons are attributed to the action of 8 kinds of {110}[111] slip systems . The results of several researchers, showing recrystallized {111}[uvw ] grains from the rolled matrix having {111}[uvw], were also discussed in this paper from the view point of [112]-rotation, and an alternati ve idea on the formation of [111]//ND texture has been proposed.
