Torsion Deformation

The effect of precipitate on microstructure evolution and hardness of Al-Cu alloy during torsion deformation has been investigated, by comparing the evolution of microstructure in aged Al-2wt.% Cu alloy with commercial purity aluminum (1100Al). The microstructure evolution is studied by Transmission Electron Microscopy and Electron Backscatter Diffraction, and hardness is measured using Vickers hardness measuring instrument. It is found that the presence of precipitate enhance the grain refinement and hardness of Al-Cu alloy. By applied equivalent strain of 3.26, the (sub) grain size of 86 nm is achieved. In contrast, the presence of precipitate is found to be inhibiting the development of high angle grain boundary.
