Effect of Annealing Temperature on Texture, Microstructure and Properties of Ti-IF Steel

Composition design and process control of Ti-IF steel by CSP process is introduced in this article,and through simulation of batch annealing in laboratory,the effect of annealing process on texture,microstructure and properties is researched. The textures and microstructures of Ti-IF steel treated with different annealing process are analyzed by optical microscope, electron back-scatter diffraction(EBSD) and X-ray diffractometer(XRD). The results indicate that with the increase of annealing temperature,{111} texture is enhanced,and r value increases,resulting in the improvement of uniformity of microstructures and deep drawability. It can be concluded that the increase of annealing temperature is favorable to obtain excellent comprehensive properties of Ti-IF steel.
