| Abstract |
The macroscopic texture and r-value (width-to-thickness plastic strain ratio in uniaxial tension) anisotropy in Ti-added high strength IF steels were investigated. In order to consider the effect of carbon on r-value anisotropy in the steels, metallurgical parameters (grain size, precipitates and texture) in the hot-rolled, cold-rolled and annealed specimens were investigated. Initial grain size in the hot band and distribution of precipitates in the annealed specimen were main metallurgical factors influencing the macroscopic annealing texture and r-value anisotropy in the Ti-added high strength IF steels. Predictions of r-value anisotropy were carried out using a full-constraints Taylor polycrystal model. The predicted r-value anisotropy were in good agreement with experimental data. |
