| Abstract Scope |
In this work, the effect of asymmetric rolling parameters on the mechanical properties of two aluminum alloys was investigated. The asymmetric rolling (ASR) process is known as a process capable to improve the properties of the material through microstructure refinement and development of a shear component of texture that leads to an improvement of strength and plastic anisotropy. An asymmetric mill equipped with two identical rolls commanded by independent motors was used to analyze the effect of reduction per pass, asymmetry factor and the rolling route. The two materials, AA6022 and AA6061, modified by ASR, were analyzed by uniaxial tensile test, hardness test and Electron Backscatter Diffraction technics. It was observed a strong increase of yield stress and ultimate tensile strength in detriment of formability, being more accentuated for AA6061 compared to AA6022. Regarding the texture evolution, shear texture components are linked to a higher reduction per pass. |
