| Abstract Scope |
6061 aluminum alloy (6061AA) is a heat-treatable Al-Mg-Si alloy known for its excellent formability, corrosion resistance, and moderate tensile strength. This study aims to enhance the strength of 6061AA while maintaining its inherent advantages by fabricating 6061AA-carbon (6061AA-C) thin films through co-sputter deposition of 6061AA and graphite targets. Microstructural analysis showed that the carbon atoms were uniformly distributed within the aluminum alloy matrix through this fabrication technique. Subsequently tensile tests were conducted using a custom-built micro-tensile tester. The 6061AA-C films exhibited an increased tensile strength while maintaining its failure strain compared to pure 6061AA films. However, it was demonstrated that excessive carbon content resulted in a decrease in both tensile strength and ductility. This result can be explained by the different strengthening mechanisms occurring in the co-sputtered 6061AA-C thin films: the aluminum alloy undergoes substitutional solid solution strengthening, while the carbon addition induces interstitial solid solution strengthening and grain refinement. |
