“…With the asperities playing a crucial role in bonding, it is also conceivable that asperity geometries be modified to enhance plastic shear strains and thus promote bonding. Such surface modification has been found to be beneficial in roll bonding (Liu et al, 2008).…”

“…The average volume fraction of transformed beta, calculated manually by point counting method was approximately 15%. Two 2.5mm thick Ti-6Al-4V sheets of equal dimension (150mm x 75mm) were surface ground on both sides by a portable grinding machine in order to obtain a rough surface to facilitate bonding [4]. Subsequently sheets were chemically degreased by acetone to remove any loose scales sticking on the surfaces.…”

Low density, excellent corrosion resistance, moderate strengths at high temperatures make titanium based alloys candidate materials for advanced aerospace structures. Advanced joining techniques are emulating for fabrication of complex aerospace structures. Roll bonding is one such solid state joining technique where bonding between two rough and clean surfaces is obtained under high temperature and pressure. The work horse dual phase titanium alloy Ti-6Al-4V finds extensive structural application in aerospace and space industries. In the present study, two Ti-6Al-4V sheets are stacked together and encapsulated in a mild steel can followed by evacuation and hot crimping. The pack is extensively deformed to ~84% reduction in thickness employing conventional hot rolling mill. Partially roll bonded 0.74mm thick sheets were obtained and microstructural evolution was studied using light microscopy and scanning electron microscopy. The incompletely bonded interface was analyzed through elemental mappings by Electron Probe Micro Analyzer and compared with completely bonded region. The partially bonded region revealed the presence of aluminium oxide at the interface which possibly could have hindered complete bonding at that region. The room temperature tensile properties of as-roll bonded Ti-6Al-4V nearly approaches the base material properties.

“…Analysis of publications. Numerous researches have clarified the influence on the bonding strength of such main parameters of the roll bonding process as a reduction [1][2][3][4][5][6][7][8][9][10][11][12][13], a temperature [1,2,4,[6][7][8][9][10]14,15], a heat treatment process [2,6,8,10,14,17,19], a surface treatment [4,19,20], a rolling speed [5,10,20], it was also studied the effect of asymmetrical rolling on bonding strength [17,21]. Researchers [5,8], who studied the roll boning process of aluminum clad sheets 1050, 1100 and medium carbon steel have found that in case of cold roll bonding the threshold of deformation for achieving bonding between layers is around 10%.…”

A flat roll bonded composite material based on aluminum matrix and reinforcing steel mesh inlets can be applied in aero-space, automotive, train, ship building, and household industries. However, the development of its manufacturing technology requires complete understanding of transformation of its components during the roll bonding process as well as an impact of technological parameters on its bonding quality. Thus, bonding properties between aluminum clad layers AA6060 and steel meshed reinforcement inlets AISI 304 (expanded sheet) and ASISI 321 (wire mesh) of roll-bonded reinforced composite have been investigated in this study. The applied reduction was 30 and 20 %, the temperature of the roll bonding process was 500 and 400℃, the temperature of the heat treatment process was 520℃ with holding time 45 minutes. During the peel test, the destruction of inlets was observed in all cases, therefore, no data were obtained regarding the correlation between the reduction magnitude and the peel strength. At the same time, the effect of temperature and heat treatment on the bonding strength between layers have been studied by means of peel test. In addition, a simulation of the hot roll bonding process of aluminum with expanded mesh inlets was developed using the finite element method (FEM) via QForm software. Conditions of FEM simulation corresponded to experimental ones and the simulation was verified with the experiment by the comparison of deformation parameters of whole composites and angles between strands during the opening of expanded mesh cells.
