“…Xiaojun and Xianjin (Xiaojun & Xianjin, 1995) developed a new technology (the details were not mentioned) to improve the drawability of Ti+ Nb stabilized interstitial free high strength bake hardened steel. The r m -value of the experimental sheet treated by the new technology is as high as 2.67, and this is the highest r m -value published so far for phosphorus-added high strength and deep drawing sheet steels with increased strength due to bake hardening.…”

“…1995). Our experimental results showed that the annealing texture gained by the new technology consists of even stronger 111 texture as compared with that by conventional technology, and the crystal orientations coi'responding to the peak values of orientation density had also been changed from conventional {111} < 112 > orientations to 111} < 110 > orientation (Guan et al 1995). In order to reveal further the cause why these changes took place, we carefully investigate texture development during annealing in the new and the conventional technology respectively.…”

The texture change in an ELC-BH sheet steel with very high r¯ value produced through a new technology invented in our laboratory during annealing has been successfully investigated by means of the methods of ODF analysis and metallographic structure observation in this paper. Thus, the developmental law of the texture which consists of even stronger {111} texture with main {111} < 110 > components as compared with that of texture in conventional technology during annealing has been discovered. The experimental results are described as follows: 1) It is different from conventional technology that the velocity of both nucleation and growth to the recrystallization grains of {111} < 110 > orientations is always larger than that of {111} < 112 > orientations. 2) The cause why this law is engendered may be related to that the advantage, that cold deforming stored energy of {111} < 110 > orientation grains is higher than that of {111} < 112 > orientation grains, is brought into fully play in the cold rolled sheet with stronger {111} texture during annealing.

To give good drawability, steel needs high volume fractions of the annealing texture component f111ghhkli and a low fraction of *f100gh0kli. This is achieved in conventional N b ‡ Ti stabilized interstitial free (IF ) steels by a cold rolling (CR ) reduction of 85 per cent followed by annealing at 750-850 8C for a few minutes. In this research, a detailed investigation of two-stage deformation processes was undertaken in which the total reduction in thickness was kept constant at 80 per cent, with a rst and second rolling interrupted by recrystallization (R X) before the nal recrystallization anneal was made. The texture produced is a rather at g recrystallization bre of relatively high intensity at a reasonable nal grain size. A second experiment, involving rolling ferrite at 700 8C, produced a strong rolling texture and a well-developed f111ghhkli texture after annealing at 710 8C, and so this material was also subjected to further rolling and annealing. The intermediate annealing between warm rolling (WR ) and subsequent cold rolling signi cantly improved the intensity and uniformity of the nal f111g texture compared with metal that was cold rolled without intermediate annealing. An investigation into the mechanisms involved in recrystallization revealed that the f111ghhkli oriented grains were subject to orientation splitting involving rotations around h111iN D , and this process of deformation banding produced the necessary lattice curvature for nucleation of the f111g recrystallization texture components essential for good deep drawability.
