Effect of Coil Temperature on Microstructure and Texture Evolution of an High Strength Nb-IF Steel Sheet

摘要：

　　Effect of coil temperature on the texture and microstructure evolution during cold rolling and annealing were investigated by OM,ODF and EBSD.The results indicate that the 223〈110〉 and 114〈110〉 textures appeared after cold rolling are inherited followed by annealing,whose intensities would be higher as the coil temperature decreased.Lower coil temperature could improve the uniformity of grain size and increase the fraction of low-angel grain boundaries as well as coincidence site lattice boundaries.And the 111//ND texture is improved in the lower coil temperature cold and annealing steel sheet,which is beneficial for the deep-drawability.
