Abstract
In this paper, a textural analysis on the planer anisotropy of r-value was carried out using extra low carbon steel sheets cold rolled at 80% and 90% with a hot band grain size of 28μm and 54μm respectively. For a detailed analysis, a model for calculating r-values from ODF-data of texture was used and the influence of each or a group of crystal orientations of the recrystallization texture in question on the planer anisotropy of r-values was studied. The following results were obtained: A development of {111} 〈110〉∼{443}〈110〉∼{332}〈110〉∼{221} 〈110〉 enhanced the V-type planer anisotropy of r-values. A decrease in the intensity of these orientations by increasing the cold rolling reduction or the refinement of the hot band microstructure reduced the r-values in L and c directions and hardly affected the r-value in D direction, and as a result, the V-type planer anisotropy of r-values was improved. On the other hand, an increase in the intensity of {111},{334} orientation by increasing the cold rolling reduction or the refinement of the hot band microstructure raised r-values in sequence of L<D<C directions and contributed to reduce the V-type planer anisotropy of r-values as a whole.
