“…Previous investigations have clarified that the initial thickness affects the location of the bond point and, hence, changes the bond strength. 38 Movahedi et al 24 have investigated the effect of initial thickness on the bond strength of Al-3003 alloy and pure Zn strips. They found that by decreasing the initial thickness of both strips, the bond strength increases and the threshold reduction decreases.…”

“…[1][2][3] The solid state joining technique in the CRB can be applied to a large number of materials, which may be the same, possessing identical attributes, or may be different, possessing widely varying mechanical and metallurgical properties. [1][2][3] A number of studies have investigated the microstructures and mechanical properties of layered alloys and composite strips or foils produced by the CRB process, including Al, [4][5][6][7][8][9][10][11][12] steel, 13 Cu, 14 Al-Cu, [15][16][17][18][19] Al-Ti, [20][21][22] Al-Mg, 23 Al-Zn, 24 Al-steel, [25][26][27][28][29][30][31][32] Ag-Cu, 33 Cu-Nb, 34 Ti-Ni, 35 closed cell aluminum foam, [36][37][38] solid oxide fuel cell 39 and metal matrix composite. [40][41][42] In this process, bond strength is the most important.…”

Cold roll bonding (CRB), a well established and widely used manufacturing process, is a solid state bonding process to join similar and dissimilar metals. The present work offers a review of the CRB process and effective parameters on bond strength of cold roll bonded materials. The effects of different amounts of reduction in thickness, annealing treatment, initial thickness, rolling speed, rolling direction, friction coefficient and presence of particles between strips on bond strength were evaluated. It was found that higher reduction in thickness and friction coefficient, lower initial thickness, rolling speed and amount of particles were the important factors involved in improving bond strength. In addition, annealing treatment before and/or after the CRB process increased bond strength, while the effect of prerolling annealing was more pronounced. Finally, it has been indicated that bond strength of cold roll bonded fcc materials is stronger than that of the bcc and hcp materials.

“…[1][2][3][4] The cellular structure of AF plays a key role in the properties mentioned earlier. To further enhance the mechanical properties of AF, several kinds of AF-based composites [5][6][7][8][9][10][11][12][13][14][15] have been proposed. They are commonly used in energy absorbers for improving the crashworthiness of structures.…”

Herein, the mechanical properties of closed-cell aluminum foam-polyurethane composites (AF-PU composites) under cyclic compression are studied experimentally. The results show that AF-PU composites with PU coating at the bottom exhibit great deformation recovery ability and excellent reversible energy dissipation capacity, which is mainly associated with the presence of PU coating at the bottom. The high stiffness of AF-PU composites is also possessed. The reversible energy dissipation of AF-PU composites with PU coating at the bottom is primarily caused by the recoverable extrusion of PU coating at the bottom. Also, AF-PU composites with PU coating at the bottom indicate an excellent low cycle fatigue performance, which verifies the reliability of AF-PU composites with PU coating at the bottom utilized for repetitive energy dissipation applications. The results presented herein are conducive to broadening the scope of the application of closed-cell AF.

“…Such products have reduced strength and they wear easily if exposed to friction, due to their porous surface and low hardness. Several methods and procedures, like thermaly sprayed coatings [22], agehardening heat treatment [23] and surface treatment by resin [24], have been developed in order to improve the quality of the outer porous surface, and, thus, wear and corrosion resistance and mechanical properties of the metal foams. Qiao et al [25] investigated the effect of surface structure on mechanical properties of opencell aluminium foam after machining.…”

Aluminium foam elements foamed into moulds, have a porous core, surrounded by a thin layer of non-porous outer surface. This layer affects the homogeneity and mechanical properties of the element significantly. To produce functional elements, the foams can be machined to a desired end shape. Machining deforms the surface structure, which results in a reduction of strength properties. This article describes an experimental approach to determine the effects of machining parameters on the surface porosity of closed-cell aluminium foam samples. The samples were machined by incremental forming and friction rolling with precisely defined processing parameters (deformation depth, feed rate and spindle speed). High-resolution digital photos of the treated surfaces were taken and analysed using image segmentation with a multispectral threshold algorithm. The change of surface porosity was calculated for each sample, and the influence of the selected machining parameters was determined by the use of response surface methodology. The optimal machining parameters are presented.
