Cell Structure Improvement in Melt Processed Pure Aluminium Foams by Pre-treatment of Foaming Mixture

Abstract This work aims to evaluate the cell structure of aluminium foams blown by using foaming mixture subjected under ball milling and heat treatments. paper presents study on effects various pre-treatment foamed (Al) fabricated via melt route. also demonstrates how method can be used fabricate small-sized Al foams. Prior melt, containing TiH2 was pre-treated treatment in four different ways. The mixtures were characterized X-ray diffraction (XRD), Energy Dispersive Analysis (EDAX) Scanning Electron Microscope (SEM) techniques. macrostructure has been optical scanner ImageJ software. mechanical properties foam samples evaluated quasi-static compression test. XRD results revealed TiO 2 Ti 3 O phases formed treated TiH powders. SEM micrographs showed morphological changes occurred powders their distribution before after milling. EDAX reported chemical composition elements present mixtures. Ball milled not only increases number particles, but reduces hydrogen content during stage. produced from heat-treated ball-milled shows better size & with good homogeneity. However, mechanically mixed produce strength energy absorption capability.
