">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......
