The role of Goss-oriented texture for brass-type texture in nickel-based metals during cold rolling

Face-centered cubic (FCC) metals exhibit varying stacking fault energies (SFE), which predominantly lead to the development of copper-type and brass-type textures during extensive deformation rolling. However, the mechanism underlying the formation of brass-type textures remains poorly understood. This study identifies the significant role of Goss-oriented texture in driving the development of brass-type texture in nickel-based metals. Despite its importance, the Goss-oriented texture has often been overlooked in studies focusing on the rolling texture of FCC metals due to its relatively low occurrence. This investigation explores the formation of Gossoriented texture during the rolling process of nickel-based metals and its influence on microstructural deformation. Research indicates that the formation of Goss-oriented texture primarily arises from two mechanisms: dislocation slip and twinning deformation of copper-oriented grains. While dislocation slip minimally affects the microstructure during metal rolling, twinning deformation induces stress concentration and the initiation of shear bands. These factors subsequently influence dislocation slip in copper-oriented grains, ultimately leading to the formation of brass-type rolling texture.
