Abstract
The effects of niobium on the cold-rolling and recrystallization textures in low carbon steel sheets were examined using X-ray techniques and electron microscopy. In the hot-rolled strips containing niobium, numerous precipitates about 150Å in diameter were observed. These precipitates had an effect on the cold-rolling textures to increase the {111} component with cold reductions up to 75%. The {111} component decreased abruptly and the {211} ⟨011⟩ component increased for reductions greater than 75%. The recrystallization textures could be closely related to the cold-rolling textures. The recrystallization textures changed continuously from {554} ⟨225⟩ to {211} ⟨011⟩ along the loci of the R.D.-60°⁄⁄⟨110⟩ fiber texture with the cold reductions prior to annealing. It was also found that fine precipitates retarded the recrystallization and inhibited the appearance of the (110) [001] component.
