摘要
Two steps foaming (TSF) technique was proposed to prepare shaped AI alloy foam. Based on the thermal decomposition kinetics equation of titanium hydride, the relationship between two steps thermal decomposition kinetics of titanium hydride and two steps foaming AI alloy melt was studied. Two steps thermal decomposition curve of titanium hydride under increasing and constant temperature was calculated respectively. The hydrogen mass needed in the second foaming step was also calculated. Results showed that the hydrogen mass of the second thermal decomposition of titanium hydride is enough for the second foaming step in the condition of as-received AI melt foaming. Experimental and theoretical results indicate that two steps foaming technique can be used to prepare AI alloy foam with high porosity, shaped components and sandwich with AI alloy foam core.
