In this research the main purpose was finding and improving a technical and practical process to produce aluminum based foam. As a result; aluminum-A356 foam was produced using melting process, the molten A356 was alloyed by adding 4%Wt of Copper(4%WtCu-Al) to be apt for aging, then foam was produced by using TiH2 Nano scale powder as foaming agent. Ageing heat treatment cycle was performed on alloyed foam then cell structure and mechanical properties for both alloyed and not alloyed foam was compared. Results was shown cell structure for the foam with Cu is spherical with smooth layer which is crooked and elliptical that for A356-foam. The uniaxial compressive yield strength, as a result of this heat treatment cycle, was increased from 10 to 27.5 MPa, about 170% increase in yield strength. The energy absorption, was measured by uniaxial compressive loading, was shown an increase of about 160% for the aged alloy in comparison to non-heat-treated specimen. So to achieve this final properties adding 4-5 percent of Cu following the heat treatment cycle is the main result of this research. The cycle, solution process at 510 °C for 12 hours and then quenching in cold water, carrying on the process by aging at 160 °C for 3 hours culminate in best mechanical properties for A356+4%wt.Cu.
