Abstract:The primary recrystallization textures of 70-30 brass rolled at 90% reduction in thickness by cross shear rolling in single direction with 1.39 speed ratio were calculated by three dimensional orientation distribution function.It is found that the main textures of every laryer along rolling plane normal are the same as that of 70-30 brass rolled by conventional rolling, but the intensites and scatters of every texture component in main texture are different. The macroscopic statistical unsymmetry of deformation textures were carried out very well by primary recrystallization textures in process of primary recrystallization, nucleation occupies a dominant position.
