  • The equal angular pressing (ECAP) of H65 brass was simulated by using the deform-2D software by analyzing the deformation regularity and the secondary phase orientation in the ECAP process. The combined ECAP deformation experiment verified the evolution of the secondary phase orientation. The results show that, ECAP deformation process can be divided into four states: initial deformation load is gradually increased, gradual deformation load is rapidly increased, stable deformation load is fluctuated within a certain range, finished deformation load is quickly decreased; the center equivalent strain distribution of the sample along with the increasement of extrusion passes is gradually stabilized, and concentrated within 3 to 9 mm in the center of samples. Even passes can be obtained relatively homogeneous deformation; the die that in corner of inner angle is the prior place to crack. The simulation of the second phase evolution almost the same with experiment, the second phase of the central sample after odd passes deformed, the angle between deformed second phase and extrusion direction is between 30 degrees during odd passes, center and edge orientation is different during even passes. The vertical second phase in the center sample, orientation remains the same during different passes.
