摘　　要：随着节能减排对于材料轻量化的要求不断提高,镁合金在诸多领域得到了广泛应用。然而,镁合金熔体易氧化燃烧,使得镁合金构件的成形方式有限。半固态成形通过将液态金属转化为球形半固态颗粒,可减少成形缺陷并提升材料性能。半固态注射成形则结合了高压铸造与注射成形的优点,实现了半固态浆料制备和成形过程一体化,可用于生产具有复杂形状的薄壁零部件。本文综述了镁合金半固态浆料非树枝晶结构的形成机制,总结了相关的半固态浆料制备工艺,并对镁合金半固态注射成形技术进行了介绍,对镁合金半固态成形技术的未来发展进行了总结与展望。Due to the increasing requirements for lightweight materials in energy conservation and emission reduction,magnesium alloys have been widely applied in numerous fields.However,magnesium-based melts are prone to oxidation and combustion,which limits the methods used to form magnesium alloy components.Semi-solid formation can reduce defects and enhance material properties by transforming liquid metals into spherical semi-solid particles.Semi-solid thixomolding technology combines the advantages of high-pressure casting and injection molding,realizing the integration of semi-solid slurry preparation and the forming process,and can be used to produce thin-walled parts with complex shapes.This paper reviews the formation mechanism of the nondendritic structure of magnesium-based semi-solid slurries summarizes the relevant semi-solid slurry preparation processes,introduces magnesium-based semi-solid thixomolding technology,and finally summarizes and prospects for the future development of magnesium-based semi-solid forming technology.
