包含铝的镁合金用晶粒细化剂、镁合金的制造方法及利用该方法制造的镁合金
摘要：
本发明的镁合金用细化剂包含铝(Al)和锰(Mn)，其微结构内包含铝(Al)和锰(Mn)的化合物，在所述铝(Al)和锰(Mn)的化合物中，Al/Mn组成比即原子比为4～4.5的化合物的面积大于Al/Mn组成比即原子比为5.5～6.5的化合物的面积，镁熔液内添加所述细化剂的情况下，能够将晶粒细化成50～100μm。
摘要（英）：

A grain refiner for a magnesium alloy according to the present invention contains aluminum (Al) and manganese (Mn), and contains a compound of aluminum (Al) and manganese (Mn) in the microstructure thereof, wherein the grain refiner is composed of a structure in which, in the compound of aluminum (Al) and manganese (Mn), the area of the compound having an Al/Mn compositional (atomic) ratio of 4-4.5 is larger than the area of the compound having an Al/Mn compositional (atomic) ratio of 5.5-6.5. When the grain refiner is added to molten magnesium, crystal grains can be refined to 50-100 μm.
