Abstract
The evolution of microstructure and texture during isochronal annealing of a heavily cold rolled Al-0.3% Cu alloy has been characterized using electron backscatter diffraction. It is found that the rolling texture of this alloy is dominated by the Brass component and that recrystallization during annealing leads to the formation of a pronounced Goss texture. It is suggested that the development of the strong Goss texture in Al-0.3% Cu is caused by preferred growth of Goss-oriented grains into the Brass-oriented matrix.
Highlights
IntroductionCopper {112} 111 , S {123} 634 and Brass {110} 112 orientations
The rolling texture in aluminum alloys typically contains three prominent components, i.e.Copper {112} 111, S {123} 634 and Brass {110} 112 orientations
Localized shear banding at ~35° to the rolling direction (RD) is observed in the rolled microstructure
Summary
Copper {112} 111 , S {123} 634 and Brass {110} 112 orientations During annealing this texture is often replaced by a recrystallization texture with a pronounced Cube {001} 100 component, the deformation texture can be retained in recrystallized samples [1]. Another frequently reported recrystallization texture of commercial aluminum alloys is a combination of P ~{110} 111 and CubeND {001} 310 components [2,3,4]. We report a strong Goss texture observed after annealing of a heavily cold rolled Al–0.3%Cu alloy. To provide more detailed information on nucleation sites and to study the evolution of Goss-oriented grains, high-resolution EBSD analysis of large areas in rolled and annealed samples is conducted in the present work
