摘 要: 采用喷射成形技术制备的金属材料锭坯具有成分均匀、晶粒细小、内应力小、可高合金化等特点。该技术自20世纪60年代发明起，受到广泛的研究并实现产业化推广应用。我国自20世纪90年代起逐步开展了大量基于实验室条件的基础和应用研究，但许多研究者认为喷射成形材料不可避免的孔隙问题限制了其应用。随着我国喷射成形关键技术的突破，实现了大规格(d600~800 mm)铝合金锭坯的工业化生产，为围绕该技术及其高性能金属材料产品的研究、开发与应用提供新的可能。本文综述了喷射成形的原理及特点、技术现状与应用，重点围绕喷射成形高强Al-Zn-Mg-Cu合金，从整体研究进展及应用情况、显微组织与性能、变形加工技术、热处理工艺等方面进行了综述，提出研发展望，以期为喷射成形高性能Al-Zn-Mg-Cu合金的研究与开发应用提供参考。

Abstract:The metal ingot produced by spray forming technology has the characteristics of uniform composition, fine grain, low internal stress and high alloying ability. Since its invention in the 1960s, this technology has been widely studied and industrialized. A lot of basic and applied researches based on laboratory conditions have been carried out in China since the 1990s, but many researchers believe that the inevitable porosity problem of spray forming materials limits its application. With the breakthrough of key technology of spray forming in China, the industrial production of large size (d 600-800 mm) aluminum alloy ingot has been realized, which provides new possibilities for the research, development and application of this technology and its high-performance metal products. In this paper, the principle, characteristics, technology status and application of spray forming were reviewed. Focusing on spray forming high-strength Al-Zn-Mg-Cu alloy, the overall research progress and application, microstructure and properties, deformation processing technology, heat treatment process and other aspects were summarized. The research and development prospect were put forward, so as to provide reference for the research, development and application of spray forming high-performance Al-Zn-Mg-Cu alloy.
Key words: spray forming; ultra-high strength aluminum alloy; Al-Zn-Mg-Cu alloy
