Textural Characteristic of 70-30 Brass Rolled by Cross Shear Rolling in Single Direction

70-30 brass is rolled with 90% reduction bycross shear rolling in single direction with speed ra-tio 1.39.The sheet is divided into five layers alongrolling plane normal to measure macroscopic statis-tical unsymmetric textures in every layer are des-cribed and analysed by means of three dimensionalorientation distribution function.The results indi-cate that the main textures in every layer of brassrolled by cross shear rolling in single direction arethe same as the main textures of brass rolled byconventional rolling.But the intensities,peak posi-tions and scatters of every texture component in{110}<112>are different,namely,there is amacroscopic statistical unsymmetry.It is found thatthe textures in every layer of brass rolled by crossshear rolling in single direction can be considered asthe textures of brass rolled by common rolling insingle direction at identical shear forces,themacroscopic statistical unsymmetry depends on theshear forces which are exerted on the layer.
