| Abstract: | Aluminum foams were fabricated by Powder Compact Foaming(PCF) process.The relationship between the cell structures and the processing parameters such as pressure,foaming temperature,foaming time,foaming agent content and granularity was studied.Based on the effects of processing parameters on cell structure that was tested by self-made software FoamScan,optimized fabricating processing scheme was obtained.The mechanical properties of Aluminum foams with porosity 83%-87% were tested,and the corresponding compressive yield stress expression was analyzed by comparing the theory model with the experimental data.The relationships of processing parameters,cell structures and compressive properties of aluminum foams were built up. |

| Keywords: | aluminum foam powder compact foaming(PCF) process cell structure compressive property |
