| Abstract: | The developments of high strength and toughness aluminum alloy are reviewed in this paper in detail. The authors discuss the relations between its microstructures and properties as well as key mechanism of strengthening aluminum alloy. Some new heat treatment techniques, such as solutionizing, regression and reageing,etc are introduced. Some proposals are made for its futural, development and research. |
