Effect of Precipitate Size and Dispersion on Lankford Values of Titanium Stabilized Interstitial-free Steels.

Effect of Chemical Composition and Thermomechanical Processing on Texture in Hot Bands of Ti and Ti+Nb Containing Ultra-low Carbon Steels

“…The effect of Nb-and Ti-bearing precipitates on texture has been studied by many researchers who have emphasized the effect of these precipitates on recrystallization and grain growth. [18][19][20][21] Especially Nb precipitation can inhibit the recrystallization of austenite during hot rolling and lead to sharp rolling textures in austenite.…”

Effect of Aluminum Content on the Mechanical Properties of Dual Stabilized Ti–Nb Interstitial Free High Strength Steel (IF-HSS)

“…14,29,30) Following this argument, it can also be easily inferred from the TEM and SANS observations of this study that the annealed steel with high aluminum content should have a stronger g-texture and thus a better mean r-value because of the relative absence of fine precipitates smaller than 40 nm (refer to Fig. 10).…”

“…[11][12][13] For example, it has also been suggested that a dense dispersion of very fine precipitates in IF steels leads to a weak intensity of {111} texture. 14) Therefore, one view of texture optimization holds that in order to improve the formability performance of IF steels the ferrite matrix should be free of interstitial elements and the precipitation that takes place should be coarser. In order to accomplish these objectives it is important to optimize the processing conditions.…”

The Influence of Microstructural Features and Mechanical Properties on the Cold Formability of Ferritic Steel Sheets

“…Weakening of grain boundary strength also reduces the formation of detrimental {110} texture. 15) It is known that IF steels with the same chemical compositions can yield different r values under varying mill processing conditions due to differences in residual solute contents, in size and dispersion of the precipitates and the d. The study of Subramanian et al 16) revealed that low slab reheating temperatures achieved removal of C to sparse and coarse dispersions of Ti precipitates exhibited a strong {111} texture and high r values, due to the higher grain boundary mobility.…”
