On the Microstructure Homogeneity of AA6061 Alloy After Cross‐Shear Deformations
Source abstract
Abstract
This work is presented to investigate the homogeneity of microstructures evolved after cross‐shear deformations imposed by a differential speed rolling (DSR) process. For this purpose, transmission electron microscopy (TEM) microstructures and through‐thickness hardness maps of AA6061 aluminum alloy samples deformed by the DSR process are investigated. The results reveal the evolution of ultrafine grained structures (≈0.3 µm) after DSR deformation. Additionally, it is found that the through‐thickness homogeneity is clearly improved as the number of the cross‐shear increases.
