摘要
随着运输和电子行业对轻质材料的需求不断增长,镁合金成为现有合金的良好替代品。然而,镁合金综合力学性能的不足大大限制了其作为结构组件的应用。晶粒细化作为合金强化的最主要方式之一,因其能同时提高材料的强度和塑性而倍受关注。综述了镁合金铸造成型工艺中晶粒细化的研究进展,系统地讨论了不同工艺方法的细化机理、工艺的研究现状和存在的问题,为镁合金晶粒细化进一步发展提供一些思路和参考。
With the increasing demand for lightweight materials in the transportation and electronics industries,magnesium alloys are a good substitute for existing alloys.However,the lack of comprehensive mechanical properties of magnesium alloys greatly limits its application as structural components.Grain refinement,as one of the most important ways of alloy strengthening,has attracted much attention because it can improve both the strength and plasticity of the material.The progress of grain refining in magnesium alloy casting process is reviewed,and the refining mechanism,research status and existing problems of different process methods are systematically discussed,so as to provide some ideas and references for the further development of grain refining of magnesium alloy.
