Texture developments and deformation structures have been investigated in silver poly-crystals rolled at the temperatures between 293 and 473 K. In the specimens rolled at 293 K an alloy type texture develops and shear bands occur in the grains detormed by mechanical twinning, while in those rolled at 423 K a pure metal type texture appears and the shear bands are scarcely formed so that deformation by multiple slip is activated in each grain. Both of the textures are explained in terms of the effects of shear banding on the development of rolling texture. It is concluded that the texture transition from the alloy type to the pure metal type can be explained by the diminution of mechanical twinning followed by shear banding with increasing rolling temperature.
