The cell structure refining mechanism shows that adding Mg decreases the surface tension of the aluminum alloy melt and hence to increase the bubble stabilization. Adding nuclear forming agent increases the nuclei of heterogeneous nucleation. Adding pre-heating foaming agent postpones its decomposition, hence to increase the uniform of foaming agent dispersion. Stirring within the middle stage of foaming agent rapid decomposition breaks up big bobbles to fine bobbles, hence to reduce mean cell diameter.

孔径细化机理分析表明，Mg的作用在于降低铝熔体的表面张力，提高气泡稳定性；形核剂的作用在于增加气泡非均匀形核的核心；发泡剂氧化预处理可以推迟和延缓发泡剂的分解，提高发泡剂的分散均匀性；搅拌发泡的作用是在发泡剂剧烈分解的中段，通过搅拌搅碎气泡，减小平均孔径。
