| 摘 要： | The commercially pure copper with dimension of 80 mm×20 mm×4 mm was used for equal channel angular pressing （ECAP）, of which their outward appearance coordinate is corresponded with that of rolling deformation modes. Cold-deformed texture was investigated. The results show that the texture character in pure copper processed by ECAP is related with intersection angle （Ф） of the die channel. When Ф is 90° and the sample is extruded for one pass, its texture consists of α and β orientation lines including mainly C, B, S and Goss components, moreover a little rotated cube is found. When Ф is 135°, as extrusion pass increases, the weak texture forms on the scope of deviation from rotated cube （ψ=0°, θ=0°, Ф=45°＋15°） and develops to the ψ=45° fiber mainly including rotated cube. When Ф is 120°, the texture is ψ=45° fiber mainly including rotated cube that is maintained constant as extrusion pass increases.

| Abstract: | The commercially pure copper with dimension of 80 mmx20 mmx4 mm was used for equal channel angular pressing (ECAP), of which their outward appearance coordinate is corresponded with that of rolling deformation modes. Cold-deformed texture was investigated. The results show that the texture character in pure copper processed by ECAP is related with intersection angle (Φ) of the die channel. When Φ is 90° and the sample is extruded for one pass, its texture consists of α and β orientation lines including mainly C, B, S and Goss components, moreover a little rotated cube is found. When Φ is 135°, as extrusion pass increases, the weak texture forms on the scope of deviation from rotated cube (ψ=0°, θ=0°, φ=45°±15°) and develops to the ψ=45° fiber mainly including rotated cube. When Φ is 120°, the texture is ψ=45° fiber mainly including rotated cube that is maintained constant as extrusion pass increases. |
