Abstract Scope |
Cold angular rolling process (CARP) is a new severe plastic deformation (SPD) technique, which can refine microstructure and greatly increase their strength of sheet metals without any length limitations at room temperature and fast processing speed. CARP features a combination of cold rolling and equal-channel angular process (ECAP). Thus, CARP allows of multiple passes similar to the general ECAP operation, so that a desired microstructure and mechanical properties can be achieved in the processed metallic sheets. The current study demonstrates successful copper sheet processing at ~278K at 5 mm/sec. Structural evolution and mechanical property changes of the processed Cu sheets are examined by X-ray diffraction analysis, and optical microscopy, Vickers microhardness measurements, and tensile testing coupled with the digital image correlation method. Moreover, the finite element method was utilized for evaluating the experimental results and capabilities of CARP. |
