Aluminum foam sandwiches (AFS) were successfully prepared by a powder metallurgical method. TiH2 powders were pre-treated in air at 450°C and 500°C for 2h in order to clarify the effect of oxidation treatment on AFS in comparison to those as-received. The decomposition curves of as-received and oxidized TiH2 powders were monitored using DSC. The macro-morphology, expansion ratio, interfacial bonding and cell structure of AFS were systematically investigated. The results show that the AFS utilize TiH2 powders oxidized in air at 450°C for 2h exhibits the best performance, under which conditions the effective bonding between the panel and core, 200% of the expansion rate and uniform pore structure of AFS have been achieved. |
