Microstructure Researches of Metallic Composite Foams Based on AlMg Alloys Oana Bălţătescu1,a *, Catalina Nuţescu1,b, Ioan Rusu1,c, Costel Roman1,d & Ioan Carcea1,e 1Technical University “Gheorghe Asachi” of Iaşi – Romania, Department of Materials Science and Engineering Blvd.
Abstract: Composite materials are the most advanced class of materials invented and produced by humans in modern times as well as a challenge for the future in the field of scientific and technological performance.
They are generally materials with unusual performances on the relationship between properties and specific gravity.
Stabilized Aluminum Foams (SAF) are new class of materials with low densities and novel physical, mechanical, thermal, electrical and acoustic properties.
