Effects of ARB cycles and holding temperature on density of aluminum foam

Metal Foams are a group of engineering materials which have many interesting properties that categorize them as advanced materials. Various techniques have been introduced for producing different types, closed cell and open cell metal foams. The aim of this research is to study one of recently introduced process, ARB (Accumulative Roll Bonding), for manufacturing aluminum foam. Numbers of ARB cycles on pre-strips, included TiH2 particles as blowing agent, were 2, 4, 6 and 8 respectively. It was noticed that increasing ARB cycles is very effective on blowing agent dispersion in aluminum matrix. Samples were heat treated in temperatures, between 620-660 Celsius. Microscopic study using SEM and density measurements were performed on specimens showing that the best result can be obtained at 650 Celsius.
