Evolution of the texture and mechanical properties of 2060 alloy during bending

Abstract

In this study, we examined the evolution of the texture and mechanical properties of 2060 (T8) alloy during bending. A pixel rotation method (PRM) was proposed and used to characterize the textural evolution during bending determined by electron backscatter diffraction. The results showed that the textural components changed insignificantly, with the exception of a decrease in the cube texture. The tensile and yielding properties of the alloy were evaluated at three different orientations with respect to the rolling direction. The mechanical strength was found to increase in three directions with decreasing bending radius; thus, it was concluded that the 2060 (T8) alloy sheet satisfies the usage requirement after bending deformation.
