Abstract
A texture of a heavily cold-rolled copper sheet was studied by means of the direct observation method using an electron microscope. Dislocations of high density uniformly distributed and no remarkable features were found in the microstructures except clear band structures locally formed. The ratio of linear dimensions of regions with (011), (112), (001) and other orientations was 55:27:5:13. The region with the (011) or (112) orientation formed a uniform structure, while the region with the (001) orientation was found in a band structure. The [\={2}\={1}1] direction in the (011) plane, the [2\={1}1] direction in the (011) plane, the [11\={1}] direction in the (112) plane and the [100] direction in the (001) plane were almost parallel to the rolling direction with the highest probability. The orientation scattering of them about the normal to the rolling plane was found to be about ±15, which coincided with the result obtained from the X-ray pole figure.
