Abstract

The textures of warm rolled low carbon and Ti-bearing extra low carbon steel sheets have been investigated using ODF's ECC-ECP (electron channeling contrast-electron channeling pattern) and selected area electron diffraction and the following results were obtained: (1) The main orientation of the low carbon steel sheet was near {113}〈110〉 while that of Ti-bearing extra low carbon steel was near 〈111〉//ND. (2) The recrystallization of the low carbon steel occurred mainly from deformed {100} grains while the main nucleation sites in the Ti-bearing extra low carbon steel were the grain boundaries of the deformed {111} grains. (3) The main orientations of grains recrystallized from deformed {100} grains are {100}〈110〉-{112}〈110〉 for both steels. (4) The orientation of the grains recrystallized from the deformed {111} grains of the Ti-bearing extra low carbon steel is mostly near 〈111〉//ND and that of the low carbon steel is mainly near {114}〈110〉. This difference is discussed in terms of the influence of carbon in solution on the crystal rotation at nucleation sites. (5) It is concluded that the different recrystallization textures formed in the two steels is explained by the difference in the preferred nucleation sites and in the local crystal rotations in the vicinity of grain boundaries.
