| 英文摘要: |
| In order to improve the formability and avoid thermal distortion of formed part during heat treatment, a novel technology named hot forming-quenching integrated process has been developed for aluminum alloy forming. The technology combines hot forming and quenching together in one operation where the sheet is transferred to the forming mould in a fast manner after solid solution and then intra-mould quenching is performed and the strength is finally improved by aging.It exhibits good formability because forming process is finished mainly at the temperature close to SHT temperature. Die quenching is beneficial to freeze the supersaturated solid solution and reduce thermal distortion so as to improve formability and guarantee the strength and the precise dimension. In this paper, the key technologies and latest developments of hot forming-quenching integrated process were introduced. Experimental and numerical studies on the integrated process were summarized and reviewed. Finally, the further research directions were proposed. |
