“…Moreover, the nearly zero solid solubility of iron in aluminum alloy is readily to promote the formation of intermetallic compounds. 6) Several solid state welding methods have been investigated to join steel and aluminum alloy, including explosion welding, 7,8) ultrasonic welding, 9) magnetic pressure welding, 10,11) friction welding [12][13][14] and friction stir welding. 15,16) The solid state welding techniques are expected to restrain the growth of the intermetallic compound layer within a permissible limit, which has been identified as 10 μm thickness, 17) but the adaptability of these methods is restricted in automotive industry due to equipment configuration.…”

Dissimilar materials of H220 Zn-coated high strength steel and 6008 aluminum alloy were welded by median frequency resistance spot welding. Interfacial characteristics and kinetics of growth of intermetallic compound layer at steel/aluminum interface in the welded joint were investigated. The intermetallic compound layer was mainly made up of η-Fe2Al5 and θ-FeAl3 phases, and its morphology and thickness varied with positions along the interface. The growth behavior of the intermetallic compound layer was dominated by η-Fe2Al5, which exhibited parabolic characteristic. The growth coefficient of η-Fe2Al5 could be expressed as with k0 of 132 m 2 /s and Q of 239 kJ/mol. The kinetics of growth of the intermetallic compound layer indicated that its formation and growth were mainly driven by reactive diffusion between Fe and Al atoms, and hence the thickness and morphology of the layer were dependant on interaction time between liquid aluminum alloy and solid steel, and also interfacial temperature history during welding. The brittle intermetallic compound layer at the steel/aluminum interface was the weak zone where cracks inclined to derive and propagate during tensile shear testing. The fracture surfaces of the welded joint displayed mixed fracture morphology with both brittle and ductile features.

“…Various methods have been developed to join Al alloy to steel, including solid-state bonding methods, such as friction welding, 3 diffusion bonding, 4 explosive welding 5 and ultrasonic welding, 6 as well as welding-brazing techniques such as gas tungsten arc welding (GTAW), 7 cold metal transfer welding (CMT), 8 gas metal arc welding (GMAW), 9 laser welding, and laser-arc hybrid welding. 10,11 Solid-state bonding methods can efficiently suppress formation of Al-Fe IMCs in a joint interface due to low heat input to the base metal.…”

“…The conclusions indicated that a welding window for these two metals exists, but it is too narrow to obtain a nice bonding interface. Some other researchers have done work on Al-Steel plates by explosive welding, but few in a cylindrical geometry [7][8][9][10].…”

Abstract:In order to solve the aluminum surface ablation issue of Al-Steel bimetallic pipes manufactured by the explosive welding technique, a novel explosive welding system has been designed to weld Al-Steel coaxial pipes. The stand-off distance was chosen according to an empirical formula. A special Explosive Cord with an aluminum coating was used as the explosive. Four experiments were performed using Explosive Cords 1, 2, 3 and 4, respectively. In each experiment, three reliable PVDF (Polyvinylidene Fluoride) piezoelectric film sensors were used to sample the impact pressure between the parent pipe and the flyer pipe along the detonation direction. p-t Curves were obtained at different points on the bimetallic pipe manufactured by Explosive Cord 1. In order to observe the inner surface and to judge the bonding interface, specimens were cut along the axial direction. BSE (Backscattering Electron) images of the interfaces were obtained. According to these pictures from all of the specimens cut along the axial direction, the surface ablation phenomenon has disappeared. The bimetallic pipe manufactured by the new welding system using Explosive Cord 3 has an irregular wavy interface, between micro and small wavy interface, which is one of the best bonding forms.
