“…Surface alloys developed by this technique are generally cobalt-based alloys [8,9] or nitrides [10]. Recently, several theoretical and experimental research projects have been carried out into explosion cladding [11][12][13][14][15]. Explosive cladding is a solid-state process in which controlled explosion joins two or more identical or different materials under high pressure.…”

is an open access repository that collects the work of Arts et Métiers ParisTech researchers and makes it freely available over the web where possible. Thus cobalt retains its crystallographic structure (f.c.c) after cladding process. Hardness is evaluated with reference to microstructure. Near the interface, the hardness of the superalloy is of the order of 600 HV 1 kg . In the remainder of the thickness, hardness is of the order of 500 HV 1 kg , being greater than that of the unplated superalloy (270 HV 1 kg ). The track obtained by an indentation test at the interface under a load of 100 kg exhibits no cracking. This tends to prove the good metallurgical bond at the interface.

“…At the bonding interface, temperatures are significantly higher than in the base materials. This is true also for explosion welding process, due to partial conversion of the elevated impact energy to heat which may indeed produce local melting and/or annealing in the vicinities of the interface [5]. Thus, upon cooling, the regions near the cladded interface tend to contract while hindered by the surrounding base material.…”

Abstract. Explosion welding is a solid state joining process that allows the manufacturing of corrosion resistant structural composite materials in the form of plates. In the present work, composite bimetal plates of AL-6XN superaustenitic stainless steel and ASME SA516-70 carbon steel produced by explosion welded were studied. Post-weld annealing for stress relief was conducted at 600 °C for 30min and the materials were examined in both the as welded and heat treated conditions. The microstructure of the weld was characterized by optical and scanning electron microscopy and the variation of hardness across the cladded interface was determined by applying Vickers microhardness. The residual stresses generated by the explosion welding process were analyzed by X-ray diffraction using the sin 2 ψ technique. The cladded interface exhibited a wavy morphology, characteristic of high bonding strength in explosion welds and the variation of hardness was found to be strongly influenced by strain hardening at the cladded interface. Elevated tensile stresses (700 ± 30 MPa) were present after explosion welding. Application of the proposed heat treatment allowed for significant stress relaxation, with a final tensile stress of 93 ± 10 MPa.

Influence of long-lasting heat treatments on the structure and properties of the zirconium-steel bond

et al. 2017

Abstract. The explosive welding technology is related to the dynamic impact of the clad onto base material. These results in significant microstructural changes of the bonded materials, the increase of internal stresses and the strain hardening of layers near the interface. In order to eliminate these unfavorable effects, it is advisable to carry out proper heat treatment. The paper presents the results of structural examinations and mechanical properties of bimetal zirconium -carbon steel, after longlasting heat treatment. Bimetallic samples were annealed at 600 o C for 1, 10, 100, 500, 1000 hours. Microscopic examination were used to the analysis of microstructural changes, whereas systematic microhardness measurements and static tensile test to evaluation of the mechanical properties. It was found that the temperature has a beneficial effect on the changes in the bond zone and for longer annealing times a systematic decrease of the strength properties of the tested bimetal was observed. However, essential for the clad mechanical properties changes were observed in carbon steel plate. After short annealing (times of 1h and 10h) only small microstructural changes due to processes of recovery and recrystallization were observed in layers near the interface. The increase of annealing time was conducive to grain growth and carbon diffusion in the interfacial layer from steel towards zirconium.
