Title: Study on the foaming structure of sandwich layer of aluminum foam sandwich
Abstract: Author studied the production technology of aluminum foam sandwich prepared by roll-bonding/powder metallurgy foaming process in this paper,and analyzed the effect of main technological conditions on foaming structure of sandwich layer,and optimum technological parameters were finally obtained.The results show that the roll-bonding technology can make the core powder tighter and can get the beneficial conditions for forming.The best foaming temperature was 615 to 620℃,and oversize connected pores occurred when foaming temperature was too high.Foaming time had also obvious effect on the solidification process of foaming body,and the foaming layer sank when time was too long.The excellent foaming structure was got when foaming temperature is 620℃and foaming time is 4 to 6min.
