| Abstract Scope |
Aluminum sheets were processed using a new continuous processing technique called cold angular rolling process (CARP) at room temperature. The microstructure and mechanical properties were characterized before and after CARP. Electron backscattered diffraction (EBSD) results showed no grain refinement, but a progressive increase in geometrically necessary dislocation density with increasing passes of CARP in Al-1100. Vickers microhardness and microtensile testing showed corresponding increasing in hardness and strength. To understand the interactions between dislocations and precipitates during CARP, Al-6061 sheets were aged at different temperatures and then processed by CARP. EBSD and transmission electron microscopy was used to characterize the precipitate and the dislocation distribution on the cross-section along the thickness of the Al-6061 sheets. The relationship of these changes to the measured mechanical properties are described. This study provides detailed microstructure characterization from the microscale to the nanoscale for this new processing technique. |
