Fabrication of ultrafine grained Al/Mg multilayered composite by high pressure torsion
Fabrication of ultrafine grained Al/Mg multilayered composite by high pressure torsion
In this paper, commercially pure Al and Mg are employed to fabricate ultrafine grained Al/Mg multilayered composites by high pressure torsion (HPT) at room temperature. The bonding quality is examined by OM, SEM+EDS and FIB+TEM. Hardness distribution in the cross section of the interface is characterized by micro-Vickers hardness and Nano-indentation. Microstructure observation shows that tomography of the Al/Mg multilayered sheet is influenced by the accumulative strain and microstructure and texture of the materials in as-received condition. Nanoindentation test shows that hardness of interface of the Al/Mg multilayered sheet is higher than the Al and the Mg sheets, which indicates solid solution and/or intermetallics formed on the interface of the Al and the Mg sheets during high pressure torsion.

Abstract
In this paper, commercially pure Al and Mg are employed to fabricate ultrafine grained Al/Mg multilayered composites by high pressure torsion (HPT) at room temperature. The bonding quality is examined by OM, SEM+EDS and FIB+TEM. Hardness distribution in the cross section of the interface is characterized by micro-Vickers hardness and Nano-indentation. Microstructure observation shows that tomography of the Al/Mg multilayered sheet is influenced by the accumulative strain and microstructure and texture of the materials in as-received condition. Nanoindentation test shows that hardness of interface of the Al/Mg multilayered sheet is higher than the Al and the Mg sheets, which indicates solid solution and/or intermetallics formed on the interface of the Al and the Mg sheets during high pressure torsion.
