The results show that a difficult-sheared region exists in the vicinity of the inner corner of the die channel; a dead zone at the outer corner of the die channel and obvious uniform shear deformation at the middle region of sample during ECAE processing are formed. The less-sheared regions caused by friction resistance are observed at lower and top parts, which are symmetric and gradually extend to the inner part along the sample longness. The less-sheared region percentage increases with ECAE processing.

结果表明：挤压过程中试样在模具通道内角点附近形成难变形区；在模具通道外角点形成变形死区；试样的芯部变形比较均匀，为明显的剪切变形；受摩擦阻力的影响，试样顶部和底部均出现了滞变区，该区域呈轴对称分布且沿试样长度方向逐渐向试样芯部扩展；滞变区比例随挤压的进行而增大。

An algorithm is established for compensating springback in sheet metal forming based on the theories of linearity closed loop control system, space Fourier transform, and transfer function in frequency domain as well as die experiment iteration.
