Microstructure and Texture Evolution Law of Ti-IF Steel for Extra Deep Drawing During Batch Annealing Process

摘要：

　　The variation of microstructure of Ti-IF steel of extra deep drawing grade, which having a 83%cold-rolled deformation under simulated batch annealing process at temperature ranging from 480℃ to 750℃, was studied by using optical microscopy, X-ray diffraction(XRD) and metallographic micro-hardness tester.The evolution of texture during the recrystallization process was analyzed by Orientation Density Function(ODF).The results show that, the recrystallization temperature of experimental steel is 620-630℃, and the recrystallization process can be accomplished within lh at660℃.Four major textures after cold rolling are observed as follows,001 < 110>, 111 < 110>, 111 < 112> and 112 < 110>, respectively.At the early stage of recrystallization annealing, texture evolves fromllltoγ-lll, which is quite beneficial to achieve high deep drawing performance, the texture 001<110> and 112<110> change marginally, as the annealing temperature rises up to 720℃, texture 001<110> and 112<110> change into fiber textureγ- 111 .After annealing, 111 < 112> and 111 <110> textures become the two main types.
