In this paper, the heat transfer performances of aluminum metal foams, placed on horizontal plane surface, was evaluated in forced convection conditions. Three different types of contacts between the sample and the heated base plate have been investigated: simple contact, brazed contact and grease paste contact. First, in order to perform the study, an ad hoc experimental set-up was built. Seco...

Metals foams are attracting great interest in aerospace, automotive and military fields. Particularly, the closed-cells aluminum characterized by peculiar properties, such as low specific weight coupled with high energy absorption capacity, stiffness strength reduced thermal electrical conductivity. For above reasons, can be effectively used core of sandwich structures, replacing traditional ho...

Steel foam offers potential advantages over aluminum foams and other metallic foams. The inherent strength of steel combined with the reduced density of foam presents an attractive material with greater strength and modulus than light alloy foams, greatly reduced density relative to solid steel, and efficient energy absorption. However, thus far there have been few reports describing efforts to...
