| Abstract Scope |
The cold angular rolling process (CARP) is developed as a continuous severe plastic deformation technique, which can process metal sheets without any length limitations at room temperature. CARP contains cold rolling and equal-channel angular process components. The sheet thickness is kept consistent before and after CARP, allowing multiple passes of the sheet. This study is aimed to evaluate the capability of CARP by processing copper (Cu) sheets for repetitive passes. The CARP-treated sheets are examined by lab-scale X-ray and high-energy synchrotron X-ray diffraction to investigate the evolution in microstructure and texture, and by tensile testing with digital image correlation method to identify the bulk mechanical properties with strain distributions. Comparing the reported continuous and multiple-step processes on Cu and its alloys, the present study confirms CARP is potentially a useful sheet process for strengthening ductile metals. |
