and the component of the matrix of closed-cell foamed aluminum on its corrosion resistance were studied. The results indicate that the corrosion resistance of foamed aluminum is worse than that of compact aluminum...; The corrosion resistance can be improved by adding rare earth into aluminum and aluminum alloys. The feasible approaches to improve the corrosion resistance were also discussed. Key words: closed-cell aluminum......

Study on the Interface Bonding and Bending Fatigue Properties of Aluminum Alloy Foam Sandwich () 摘要:Foam materials have many attractive properties because of their low-weight and cell structure. By sandwiches with an aluminum-foam core, it is possible to obtain higher structural stiffness and rigidity, maintain stability against buckling and additionally make use of the high energy......

College... 100081, China Received 16 April 2019; accepted 26 November 2019 Abstract: Combined shear-compression tests and simulations were performed on a closed-cell aluminum foam over a wide range of loading......
the onset of rupture. Finally, the aluminum foam with uniform cell structure can be obtained. The density is about 0.4 g/cm3, porosity is in the range of 85%-90% and the aperture is 4-7 mm. Key words... have occurred, and new dot material generates. Analyzed by EDX, these new generated dots may be Al2O3. Under a certain condition, we can prepare aluminum foam with uniform cell structure. Fig.5 SEM......
