چکیده
In this paper, Equal Channel Angular Pressing (ECAP) is studied using Toric Prominence (TP) on commercially pure aluminum. ECAP is one the most popular SPD processes. During this process the material is subjected to severe deformation causing extreme changes in mechanical and metallurgical properties of workpiece. The mechanical properties were studied as a function of TP Height (TPH). In this study, different heights of 14, 16, 18mm were studied. The finite element simulations were carried out using Deform 3D. Finite element modeling shows that the values of the equivalent plastic strain and its distribution, equivalent stress and deformation forces depend extremely on TPH and its profile. The numerical results show that effective strain and deformation force are increased with increasing of TPH.کلیدواژه ها

اطلاعات بیشتر در مورد COI
COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
