Resumo


Interesting properties of metal foams such as light weight, good energy absorption and low thermal
conductivity, have promoted the development of new processes to improve properties without sacrificing
productivity. This study aims to verify the uniformity pore distribution in an aluminum alloy foam obtained
by Casting - Dissolution Process, using a nondestructive analysis. In order to evaluate mechanical properties
of a metal foam using computational numerical models, the use of a small reconstructed section of the sample
representing an entire volume of metal foam, was validated. In conclusion, it was possible to determine that
all parts of the sample have the equivalent superficial area and volume.
