SPATIAL ORIENTATION DISTRIBUTION OF CRYSTALLITES IN COLD-ROLLED Al-KILLED STEEL SHEET DURING RECRYSTALLIZATION ANNEALING

The change of texture during recrystallization annealing in low carbon Alkilled steel sheet containing 0.13% Cu has been studied by function of crystal orientation distribution. It is shown that the cold-rolled texture is composed of one component of the <111> fibre texture with fibre axis parallel to the plane normal and another component of {001} <110>. The <110> partial fibre texture with fibre axis parallel to the rolling direction is formed by the diffusion of the two components. During the recrystallization, <111> fibre texture becomes prevailing and {001} <110> component diminishes while the <110> partial fibre texture contracts gradually, therefore, the <110> partial fibre texture is not an independent one.
