中文摘要:
      为解决铝合金室温塑性差和成形后热处理变形的问 题, 发展起来了 一种铝合金板材热成形-淬火一体化新工艺。 该工艺是将热处理和热成形在同 一工步完成, 即固 溶后板材快速转℃到 模具中成形, 然后完成模内 淬火, 最后通过时效来提高其强度。 高温成形可提高板材成形性能, 模内 淬火能够保证其强度和尺寸精度。 重点介绍了 铝合金板材热成形 -淬火一体化工艺关键技术及最新研究进展, 总结了 铝合金板材热成形-淬火一体化工艺实验研究和数值模拟的研究现状。
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.
