Chapter 19

Practice of Micro Bending

Abstract

This chapter introduces the practice of micro bending and investigates the grain size effects on texture evolution of annealed and micro V-bended phosphor bronze foils with different thickness (T)/average grain size (D) ratios. The results indicate that the texture evolution during annealing is correlative with the material’s grain size effects. Annealing texture evolution of phosphor bronze represents typical α-fiber components, and when the value of T/D increases, the intensities of Goss and Brass components decrease. During micro V-bending process, less grains are likely to rotate along with bending process due to grain coordination when the ratio of T/D decreases. The stability of {110} crystallographic ...
