“…From the above mentioned detailed literature survey, major drawbacks of these techniques were they are quite costlier, not friendly to the environment, requires high technical & skilled labor etc., [29,30]. As a result, there exists a need for identifying a suitable technique for joining CDA 101 & AISI 1010, which can fabricate sound joints, eliminating the various drawbacks associated with other joining techniques.…”

An experimental endeavor was made to determine suitable tool geometry and ideal values of travel speed, tilt angle, pin offset distance for fabricating 5mm thick dissimilar AISI 1010 and CDA 101 joints by FSW. 2 different sets of experiments were performed at constant 1200 rpm employing tools with distinct geometries and varying combinations of tool-related parameters. Reports affirmed the attainment of flawless joints during 2 nd set of experimentation by employing a cylindrical shouldered tool (25 mm in diameter) having a cylindrically tapered pin at 1200 rpm, 40 mm/min travel speed, by tilting the tool at 2 0 , with its pin being inserted a 1.5 mm offset distance towards CDA 101 plate. Downward axial force of 7.214 kN was found to be ideal for joining these dissimilar metals and it was majorly influenced by the tool's travel speed and pin's offset distance. Presence of different sized Cu particles in AISI matrix, have led to the creation of brittle natured and large intermetallic amalgamations in nugget zone, thereby reducing the strength of fabricated defect-free weldment & leading to a diversified combination of brittle-ductile mode of fracture exhibiting a strength of 181 MPa

“…Because of its superior properties, the copper-steel composite is widely used for aerospace, metallurgy, electric power, and other applications [3,4]. At present, the preparation methods of copper-steel composite structures mainly include explosive bonding [5], diffusion bonding [6], high-energy beam cladding [7], and arc cladding [8,9], etc. Arc cladding is developed based on arc welding and has significant advantages in production efficiency, process adaptability, and cost.…”

Due to the huge difference in thermophysical properties, it is difficult to obtain a defect-free bonding interface between copper and steel. A Cu-Ni-Ti interlayer was added between a TiC-reinforced copper matrix composite coating and Q235 steel in this study to improve its interfacial bond. The influence of the interlayer on its microstructure and properties was studied by characterizing microstructure, phase composition, and wear resistance of the composite coatings. Both coatings were found to consist of α-Cu matrix, in situ-generated TiC, and Fe-rich phases. With the addition of the Cu-Ni-Ti interlayer, the high-hardness unmixed zone at the interface was successfully eliminated due to the sufficient mixing of the molten pool. Even more importantly, liquid metal embrittlement cracks were also restrained, resulting from the Fe-rich solid solution band that reduced the contact probability around liquid copper atoms with the steel grain boundaries formed. In addition, the results showed that the microhardness of composite coatings was improved and the wear loss reduced by 4.2% after adding that interlayer, which was related to the combined action of solid solution strengthening, second-phase strengthening and grain-refinement strengthening mechanisms.

“…Explosive welding is an impressive solid state welding technique, proven to be able to weld directly dissimilar metals together. The combination of dissimilar metals is difficult to weld by any other existing welding techniques [8][9][10][11][12][13][14][15]. In the explosive welding, the detonation of high energy explosive accelerates one of the plates (a flyer plate) to be joined to collide against the other plate (a base plate).…”

The shock wave damage during explosive welding has not been reported in a flyer Mo plate of the Mo/Cu clads. However, it would be an inevitable problem in group VI elements. This study was aimed to characterize the shock wave damage in the Mo plate, that is less brittle than a W plate, of explosive welded Mo/Cu clads. Cladding at low horizontal collision velocities leading to high collision angles was expected to enhance the shock wave damage, and the clads resulted in less elongation in bending tests. On the other hand, in the clads obtained at high horizontal collision velocities (HCVs) with low collision angles, their bending elongation increased significantly. The shock wave damage penetrated from the surface of a Mo plate to the Mo/Cu interface, and thus reducing thickness of a Mo plate of bending specimens increased bending plastic strain. The shock wave damage is associated with kinetic energy imparted to the flyer Mo plate, and thus loss of kinetic energy due to formation of an intermediate layer at the interface and reducing thickness of a flyer Mo plate would be very helpful for decrease of shock wave damage.
