چکیده مقاله:

In this study, the shear spinning process and the rolling process on C۱۱۰۰۰ copper metal with a thickness reduction of ۵۰% at room temperature were performed and investigated. In the shear spinning specimen, the grains are stretched in the axis direction and elongated in the circumferential direction. In the rolled specimen, the grains are extended in the direction of rolling, and the elongation of the grains in the T-N plane is less than in the shear spinning specimen. EBSD analysis showed that the ratio of high angle boundaries to low angle boundaries in the shear spinning specimen is higher than the rolled specimen. The mechanical properties of the rolled and shear spinning specimens were investigated in three directions of zero, ۴۵, and ۹۰ degrees relative to the forming direction, which showed that the strength in all three directions was higher in the rolled specimen than in the shear spinning specimen. The elongation in the shear spinning specimen is more than in the rolled specimen. The highest amount of tensile strength in the rolled specimen is about ۳۷۰ MPa, and the highest elongation is about ۱۲% in the shear spinning specimen. Also, anisotropy in shear spinning specimens was less than rolled specimens.
