摘　　要：文摘介绍了关于铝合金板材的一种热冲压冷模具淬火复合成型工艺。该工艺在铝合金板材的成型过程中,同步完成铝合金板材的淬火,随后进行人工时效,极大地提高了铝合金板材的成型极限和强度。因此,成型件具有更轻的质量,更高的强度和更复杂的几何形状。最后讨论了使用该成型工艺的成型件在航天领域应用前景。通过对铝合金板材复合成型工艺和应用的介绍,可为我国铝合金板材成型工艺发展和工业化提供参考。A new forming process,the hybrid forming of aluminum alloys is introduced in this paper. This forming process has been applied in high-class vehicles. In this process, the aluminum alloy sheet is formed and quenched sim- ultaneously followed by a second stage precipitation period. By using this forming process, the formability and strength of aluminum alloys has greatly improved. A much lighter and stronger component, with more complex geometry can be obtained. The potential application of hybrid formed aluminum alloys components in aircrafts is discussed. This paper provides references for forming and processing of aluminum alloys, as well as the industrialization of HFQ in China.
