Abstract：

The equal channel angular pressing process of 2024 aluminum alloy with new route B was numerical simulated by finite element software Deform-3D, and the equivalent strain and its distribution law were analyzed to obtain the deformation characteristics of aluminum alloy under new route B. Then, the accuracy of deformation simulation for 2024 aluminum alloy with new route B was verified by equal channel angular pressing experiment. The results show that after multi-pass equal channel angular pressing, the deformation effect under new route B is severe and more uniform, the main deformation area of specimen is enlarged, and the head area and tail area deform fully. Due to the change of equivalent strain gradient in all directions, the uniform of equivalent strain increases firstly and then decreases with the increasing of passes. By comparing the experimental and the simulation results, the head does not warp because of the similar equivalent strain between the head and the main deformation areas.
