/min; 3) transferring the melt to the bubbly case; 4) pushing bubbly case to the furnace (650 ℃) and foaming in it for 6 min; 5) Al-Si closed- cell aluminum foam post processing[8]. For preparing... closed-cell foam aluminum by direct foaming in melt [P]. CN1320710, 2001. [8] LUO Hong-jie, YAO Guang-chun, ZHANG Xiao-ming. Technical discussion of producing foam aluminum by foaming method of molten......
="ChDivSummary">Based on the two-step nucleation mechanism, a multi-step thermodynamic model for alumina inclusion formation during aluminum deoxidation process was proposed in Fe–O–Al melt. Thermodynamic... energy change of forming the intermediate by reaction between the dissolved aluminum(Al) and oxygen(O) in the melt was calculated. The results indicated that the thermodynamics of(Al2O3)nat steelmaking......
