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 〈 110 〉 ‖ RD fiber rolling texture component by promoting the rotation about the 〈 110 〉 ‖ RD axis. This resulted in the development of the strong {112} 〈 110 〉 texture component. As to the 〈 110 〉 ‖ TD fiber texture component, it was found that, although the addition of Ti did not affect the rotation about the 〈 110 〉 ‖ TD 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.
Highlights
It is well known that the addition of Ti greatly enhances the development of the {111} recrystallization texture in low carbon steels
Orientation distributions observed at each rolling reductions were qualitatively the same as those observed in
By varying the rolling reduction in wide range and by following the rotation of various rolling texture components systematically, it was found in the present investigation that the development of the (ll0}[IRD fiber rolling texture, and the development of the (110)[ITD fiber rolling texture were strongly affected by the addition of Ti
Summary
It is well known that the addition of Ti greatly enhances the development of the {111} recrystallization texture in low carbon steels. Play important roles in the formation of the recrystallization texture. Rather little attention had been directed to the effect of Ti on the development of the cold rolling texture Since this effect might not be so pronounced as to be readily detected by the conventional pole figure method, more reliable and quantitative methods of the texture analysis should be adopted. By using the method of the three dimensional crystallite orientation distribution function analysis (Bunge, 1969), it has been found that the addition of Ti enhances the development of the {112}(110)
