综述了添加含碳变质剂,含钛、硼细化剂,碱金属,碳族元素,氮族元素,稀土元素和准晶合金对Mg-Al基镁合金晶粒细化的研究进展,系统讨论了各种细化剂对Mg-Al基镁合金的晶粒细化效果,以及对各种细化剂细化机理的研究,旨在为镁合金晶粒细化研究提供一个参考。
The present research on grain refinement of magnesium alloys is generally reviewed. The as-cast grain refinement technologies of magnesium alloys consist of additions of carbon inoculation, Ti, B refinement agents, alkali metal, carbon subgroup, nitrogen subgroup, rare-earth subgroup and quasicrystal alloys. In order to supply references for research on grain refinement of magnesium alloys, the research status and development of these as-cast grain refinement technologies of magnesium alloys are reviewed, and the refinement mechanisms of these different refinement methods are analyzed emphatically.
