The research and application of the molten metal die forging (MMDF for short) of cast aluminum alloy are very active,but the research of MMDF of wrought aluminum alloy is rarely reported. MMDF is a process technology for forming parts by using the rheological properties of metal materials near the liquidus. Wrought aluminum alloy can also be used for MMDF. Firstly, the research and app lication status of MMDF wrought aluminum alloy was summarized in this paper, and then the key technology and strengthening and toughening mechanism of MMDF wrought aluminum alloy was comprehensively analyzed. Finally, it was pointed out that MMDF wrought aluminum alloy would form a series of new materials with high-strength and light density, and there would be three main research topics of MMDF wrought aluminum alloy in the future: (1) prevention and control of cracking, segregation and incomplete forming defects in indirect MMDF of complex workpiece; (2) optimization of heat treatment process of MMDF wrought aluminum alloy; (3) integrated control of the pretreatment of wrought aluminum alloy materials,design and manufacture of the dies,selection of the equipment and MMDF process to realize the high-performance forming.
