对70/30黄铜进行不同形变量的单向轧制,用三维取向分布函数分析这种有宏观统计不对称的形变织构。根据单向轧制的受力状态描述其形成模型。结果表明:单向轧制黄铜形变织构的主织构与换向轧制的主织构相同,但其{110}〈112〉中各组分的强度和漫散程度不同,且强点偏移理想位置;有宏观统计不对称织构是由轧件所受的剪力而致,非正常滑移和剪切带的作用对其形成起着关键作用。
The 70/30 brass was subjected to one-way rolling with different deformations and the three-dimensional orientation distribution function was used to analyze the deformation microstructure with macro statistical asymmetry. The forming model is described according to the state of stress in unidirectional rolling. The results show that the main texture of the uniaxial rolled brass deformed texture is the same as the main texture of the reversed rolling, but the strength and dispersion of the components in {110} <112> are different, Offset the ideal position; macroscopically statistical asymmetry texture is caused by the shear force caused by the rolling parts, the role of non-normal slip and shear zone plays a key role in its formation.
