The design of porous metal structures is of high interest for novel lightweight industrial applications. Synchrotron tomography in combination with 3D image analysis is the suitable method to investigate these structures. In order to bring the foam production process from the laboratory to industrial scales a detailed knowledge of the control parameters’ influence on the resulting pore structur...
In this research, the reaction kinetics of TiH2 powder in contact with pure aluminum melt at various temperatures on the basis of measuring the released hydrogen gas pressure was studied. To determine the mechanism the reaction, after Solidification of samples, interface of TiH2 powder in contact with melt was studied. The results showed that PH2-time curves had three regions. In the first and...
Metal porous foams have been eliciting much interest in recent years due to their high capacity of energy absorption. The characteristics of the pores in these materials play an important role on their energy absorption capability and other properties. This study reports the fabrication of aluminum closed-cell foams by accumulative roll-bonding (ARB) technique using calcium carbonate (CaCO3) as...
Apart from density and alloy composition, the structure of solid metallic foams determines their mechanical performance. Herein, effect ambient pressure on foaming behavior AlSi6Cu4 precursors is studied. In situ X-ray radioscopy applied while in a furnace chamber pressurized up to 40 bar. The content blowing agent (TiH2) varied for each pressures chosen. foam morphology are analyzed quantitati...
