Abstract

The textures of different types of deep drawing steels were measured and analyzed using the series expansion method. The angular variation of r-value in the rolling plane was calculated from the ODF coefficients by means of different models. Comparison with experimental data shows that, in the case of sharp textures, an intermediate relaxed constraint model (pancake version) is a better predictor of the plastic strain ratio than the extreme Taylor or Sachs-Kochendorfer type calculation. This is justified as being more favorable energetically for the texture components present in deep drawing steels. The best quantitative agreement is obtained when the CRSS ratio for glide on the {112}<111> and {110}<111> slip systems is 0.95 (except for the AKDQ and IF2 grades, for which values of 0.90 and 1.0, respectively, are preferred).
