Abstract
In this study, multi-cycle constrained groove pressing (CGP) were imposed on H62 brass sheet, numerically and experimentally. The relationship between the distribution of the von Mises equivalent strain, microstructure and hardness of H62 brass was investigated. The results show that the distribution of the equivalent strain is non-uniform within samples subjected to CGP, which in turn creates the corresponding non-uniformity in the microstructure and hardness of H62 brass. With the increase of the equivalent strain the grains of H62 brass become finer and the hardness is improved. The value and distribution of the equivalent strain in H62 brass affects the plastic deformation mode at different locations within the sample subjected to CGP.
