Abstract：

In order to further study the process method of producing Cu-Al composite plate by pressing method, the experimental die scheme with detachable and replaceable die angular was designed based on the advantages of simple process and equipment for the equal-channel angular pressing method. The equal-channel angular pressing process of Cu-Al composite plate was numericaly simulated by HyperXtrude, then, five sets of schemes with the die angular of 0°, 15°, 30°, 45° and 60° were simulated and analyzed, and the pressure, stress field tensor and velocity field distribution of Cu-Al composite plate in the process of equal-channel angular pressing were discussed. The results show that when the angular changes from 0° to 60°, the pressure decreases from 186.1 MPa to 141.5 MPa. In addition, when the angular is 45°, the metal flow velocity is the most uniform.
