DEFORMATION TEXTURES AND THEIR FORMATION MODEL OF 70/30 BRASS ROLLED IN SINGLE DIRECTION
单向轧制70/30黄铜的形变织构及形成模型

70/30 brass is rolled in single direction with different rolling reductions.Three dimentional orientation distribution function is utilized to analysis the macroscopicstatistic unsymmetric textures.According to the state of received shear force,a formationmodel of macroscopic statistic unsymmetric textures is discribed.It is shown that the maintexture of deformation textrues of brass rolled in single drection is same as the main textureof deformation textures of hrass rolled in two opposite directions,but the intensity andscatting degree of every texture component in{110}<112>are different,and peak posi-tion deviats from{110}<112>position;The shear force by which specimen is receivedleads to macroscopic statistic unsymmeteric textures,abnormal slip and action of shearbands play a key role in their formation.
