Effects of different processes on microstructure and mechanical properties of H65 brass
MATERIALS SCIENCE AND TECHNOLOGY(2020)
摘要
Electron backscatter diffraction (EBSD) is used to study the effect of rolling reductions and annealing temperatures on texture evolution and special boundaries (SBs) of H65 brass. The results indicate that the texture components of H65 brass after annealed is mainly {110} (//ND), which is due to the existence of a large number of high-angle boundaries (HABs) with high mobility and a small amount of incoherent sigma 3 boundaries around the {110} component. Besides, the number of sigma 3 boundaries and the ability to produce its family boundaries such as sigma 9 and sigma 27 might be influenced by the reduction rate and annealing temperature. The textures of annealed specimens are mainly Brass{110}, S{123} and {011}, and the formation of a large number of annealing twins decreases the intensity of Cube{100}. As annealing temperature increases, {110} texture grows and twin density increases, resulting in a decrease in strength but an increase in conductivity and plasticity.
