This book describes the latest efforts to develop aluminumnanocomposites with enhanced damping
and mechanical properties and goodworkability. The nanocomposites exhibited high strength
improved dampingbehavior and good ductility makingthem suitable for use as wires. Since the
production of metal matrixnanocomposites by conventional melting processes is considered
extremely problematic (because of the poor wettability ofthe nanoparticles) different powder
metallurgy routes were investigated including high-energy ball milling and unconventional
compaction methods.Special attention was paidto the structuralcharacterization at the micro-
and nanoscale as uniform nanoparticle dispersion in metal matrixis of prime importance. The
aluminum nanocomposites displayed an ultrafine microstructurereinforced with alumina
nanoparticles produced in situ or added ex situ. Thephysical mechanical and functional
characteristics of the materials produced were evaluated using different mechanical testsand
microstructure investigation techniques. The book presents and discusses the experimental
results indetail and offers suggestions for future research directions.
