综述了镁铝合金碳质孕育法晶粒细化的机理,如溶解度理论、Al4C3异质晶核形核理论、Al-C-O化合物形核理论、碳偏析理论以及双重形核理论等,并指出现阶段各个理论存在的不足以及今后需关注的重要方向。
In this paper, the mechanism of grain refinement of magnesium-aluminum alloy by carbonaceous inoculation is summarized, such as solubility theory, Al4C3 heterogeneous nucleation nucleus theory, Al-CO nucleation theory, carbon segregation theory and double nucleation theory. The shortcomings of the various stages of the theory and the important direction to be concerned in the future.
