Abstract

The microstructural and textural analysis of the hot band reveals that the surface grains are fully recrystallised and possess the orientation elements of the shear texture, distributed along <110>// RD and <110> 30°ND fibres, while the grains, in the central layer, are partially recrystallised and their texture is composed of orientation elements of recrystallisation texture (<100>// RD) and of copper type texture (<110> 60°ND), with {001} <100> and {011} <112> as the major components, respectively. The other interesting feature of the hot band microstructure is the formation of recovery twins in the grains of {011} <112>. The short time annealing of the hot band leads to the formation of annealing twins in addition to the growth of the surface grains and to the complete recrystallisation of the grains in the central layers. Many physical processes such as the growth of the recovery twins and of the grain boundary nucleated grains contribute to the development of final annealing textures of the annealed hot band, which are like the textures present in the surface and the central layers of the hot band.
