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
