| Abstract: | Ultra - fine grain materials can be obtained through equal channel angular pressing （ECAP） by severe plastic deformation. Grain refinement can be gotten by strain and strain uniformity through equal channel angular pressing. Through simulating equal channel angular pressing of pure Ti by using DEFORM -3D software, influence of different die parameters on the deformation of metal was studied. The relationships of effective strain of the metal deformation zone among different die angles, the outer comer and the inner comer radius were obtained. It believed that the result will present an effective rule for the distribution of the metal deformation of pure titanium. |
