Development of Texture in an ELC-BH Sheet With Very High R¯-Value During Annealing

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.
