Metal foams are known to exhibit multifunctional behavior. It can offer
a unique combination of several properties that cannot be achieved by
one conventional material at the same time e.g. ultra-low density, high
stiffness and capability to absorb crash energy, and excellent sound
absorption properties. These unique combinations of properties indicate
its various potential applications such as ultra light structures, in
impact/blast absorption systems, and for sound absorption etc. Metal
foam is a generic term for a class of material, which can be classified
in terms of their structures, processing routes, and base metal. The
main aim of this research work is to produce low cost, low-density
aluminum foams by indigenously designed and fabricated equipment. This
aluminum foam material possess all the positive attributes realized in
current metal foam technology, such as high specific stiffness, low
relative density, and high-energy absorption capacity. This material is
designed to reduce the cost of production. This book will be suitable
for material scientist researching in ultra light materials.
