Recrystallization Textures of Low Carbon Steels Containing 0.61% or 0.29% Copper

Abstract

It is shown that the recrystallization texture of low carbon steel containing a small amount of copper depends on the heating rate of the final annealing. In a steel containing 0.61%Cu, the (222) pole intensity shows a maximum at about 100℃/hr and a minimum at about 50℃/hr. This behavior is interpreted qualitatively by separating the (222) pole intensity into two components; one from {111}<110> orientation and another from {554}<225> orientation. The microstructures after recrystallization are also interpreted by considering the difference in the condition for the selection of the recrystallized grains of each orientation. In a steel containing 0.29% Cu, the (222) pole intensity also shows a weak maximum at about 100℃/hr and the {111}<110> component is weak in the recrystallization texture of this steel.
