Abstract
Foams are intentionally produced porous lightweight materials useful in structural, mechanical, acoustic, thermal, and domestic applications. Aluminum and its alloy foams are gaining importance due to lower melting temperatures, lower densities, and ease of manufacturing by a variety of techniques, light in weight, good strength-to-weight ratio, good anticorrosive properties, and aesthetic in appearance. Powder metallurgy route of foam manufacturing is used to check the suitability of hydrides like LiAlH4 as foaming agents. LM2 (AlSi10Cu2) alloy is cold compacted at 200 MPa for 5 s, and at 6000C hydrogen release is observed for a minimum 5% weight of lithium containing blowing agents. This is an alternative for TiH2 foaming agent by powder metallurgy route. The foam production can be analyzed by visual observation, microstructure observation and nondestructive testing methods like X-ray diffraction analysis. A new approach of centrifugally cast powder metallurgy precursor method is introduced in this paper which can generate 45 to 60% porosity for batch production requirements at low cost.
