摘　　要：利用半固态成形技术制备高性能铝合金是现代材料成形技术的重要研究方向。介绍了几种高强铝合金的新型半固态成形技术,如倒锥形通道浇注法、流变挤压成形法、原位反应液相线铸造法等,分析了半固态成形高强铝合金的组织和性能,找出了其中存在的问题,为今后的研究开发指明了方向。It is an important research direction in modern materials forming technology to prepare high performance aluminum alloy using semi-solid forming technology. Several new preparation methods for high strength aluminum alloy with semi-solid forming technology are introduced, such as inverted cone channel pouring method, rheology extrusion molding method, in-situ reactive near-liquidus casting method. Also, the microstructure and properties of high strength aluminum alloy by these techniques are analyzed, and the existing problems are found out. Then the further research and development direction in semi-solid forming technology for high strength aluminum alloy are pointed out.
