Abstract

With the method of the crystallite orientation distribution function analysis, the development of the rolling texture was studied in detail on a Fe-0.004%C-0.20%Ti alloy cold rolled up to 90% reduction in thickness. It was found that the effect of Ti was widely different among various rolling texture components. The addition of Ti enhanced the development of the 110RD fiber rolling texture component by promoting the rotation about the 110RD axis. This resulted in the development of the strong {112}110 texture component. As to the 110TD fiber texture component, it was found that, although the addition of Ti did not affect the rotation about the 110TD axis in the range {110}001 to {554}225, it strongly suppressed the rotation of {554}225 into {111}112. As a result, strong {554}225 rolling texture component was developed below 70% rolling reduction. This component seems to provide origins of the {554}225 recrystallization texture commonly observed in the Ti-stabilized steel. Such changes in the rolling texture would be expected, since slip modes are strongly affected by scavenging of C atom by Ti, or by the presence of very fine TiC precipitate particles.
