Outline of Final Research Achievements

Fabrication of electrodeposited bulk nanocrystalline Al alloys with high strength and ductility from a dimethylsulfone bath was conducted. At first, we developed fabrication process decreasing sulfur and chlorine contents which are the embrittle elements in Al. Next, we chose Cu, Fe, Mn and Zr for grain refinement and solid solution strengthening of Al form first principles calculations. We successfully fabricated bulk Al-Cu, Al-Mn and Al-Zr alloys. As the results of tensile tests, an Al-Zr alloy exhibited tensile strength of 156 MPa and tensile ductility of 20%, which is comparable to the balance of strength and ductility in commercial non-heat-treatable aluminum alloys.
