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} (<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 Σ3 boundaries around the {110} component. Besides, the number of Σ3 boundaries and the ability to produce its family boundaries such as Σ9 and Σ27 might be influenced by the reduction rate and annealing temperature. The textures of annealed specimens are mainly Brass{110}<112>, S{123}<634> and {011}<111>, and the formation of a large number of annealing twins decreases the intensity of Cube{100}<001>. As annealing temperature increases, {110} texture grows and twin density increases, resulting in a decrease in strength but an increase in conductivity and plasticity.

不同工艺对H65黄铜组织和力学性能的影响

电子背散射衍射 (EBSD) 用于研究轧制压下率和退火温度对 H65 黄铜的织构演变和特殊边界 (SB) 的影响。结果表明,退火后 H65 黄铜的织构成分主要为 {110} (<110>//ND),这是由于存在大量高迁移率和较小的高角晶界 (HAB)。 {110} 组件周围的非相干 Σ3 边界的数量。此外,Σ3 晶界的数量和产生其族晶界(如 Σ9 和 Σ27)的能力可能受还原速率和退火温度的影响。退火试样的织构主要为黄铜{110}<112>、S{123}<634>和{011}<111>,大量退火孪晶的形成降低了立方体{100}<001的强度>.
