Behavior of closed cell aluminium foams upon compressive testing at elevated temperatures: Experimental results

Commercially closed cell aluminium foams known as ALPORAS, have undergone a set of compressive tests at ambient as well as elevated temperatures in order to study the difference in their behavior in terms of the foam's density and test temperature. A compressive stress-strain curve similar to that of dense metals has been resulted. The effect of increasing the foam's density of ALPORAS foams on their mechanical properties was opposite to that of increasing the test temperature. Furthermore the microstructure examination has been introduced. (c) 2006 Elsevier B.V. All rights reserved.
