Ti 2 SnC, as one of functional ceramics with self-healing ability, was studied in welding with Ti6Al4V (TC4) through Cu interlayer under an applied mechanical pressure 10MPa in Ar atmosphere. Electron probe microanalyses indicated that the outward diffusion of Sn from Ti 2 SnC played a critical role in the chemical composition of the joining interface. After 60 min, the reaction layers consisted of five zones: an interleaved zone (V) of β-Cu(Sn) and α-Cu(Sn), an enriched zone (IV) of Sn and intermetallic CuTi 0.5 Sn 0.5 phase, the intermetallic zones (III) and (II) composed of TiCu 4 and Ti 3 Cu 4 , a zone (I) consisting of β-Ti (Cu) phase. After shear tests, the corresponding fractographs indicated that the cracks mainly propagated in the Ti 2 SnC matrix with an intergranular fracture mode.

In this study, a novel method for manufacturing metal foam sandwich panels via selfpropagating high temperature synthesis (SHS) has been introduced. In this method, a powder mixture of metallic aluminum and copper oxide was placed in core-sheet interface, and then sandwich panel was heated under static pressure. During heating, SHS reaction (3CuO + 2Al = + 3Cu, ÁH < 0) occurred in the interface. The generated heat from this exothermic reaction caused sheets to join the core by melting the interface and nearby. In order to evaluate the shear strength of the interface, the shear test was applied to the manufactured sandwich panels and its results were compared with sandwich panels, which were produced by diffusion and adhesive bonding processes. Furthermore, by the aid of energy dispersive spectrometer and X-ray diffraction analyses, the formation of copper in the core-sheet interface and its diffusion into the sheets and the core were investigated. The results showed that metal foam sandwich panels produced by using SHS method have higher joint strength than those produced by diffusion and adhesive bonding processes, and the maximum shear strength of the interface was achieved in shorter heating time. Significantly, this innovating method for manufacturing metal foam sandwich panels can be applied as a proper and alternative method.

“…Nevertheless, the reliable welding of Mg alloys is decisive for the expansion of its application in various areas [9,10]. A series of welding methods, such as electron beam welding [11,12], brazing [13,14], diffusion welding [15,16], friction stir welding [17,18] and tungsten inert gas welding [19,20] have been developed to achieve the joining of Mg alloys. Gao et al [21] studied the microstructure features and mechanical performance of laser metal inert gas hybrid welded AZ31 Mg alloy joints.…”

In this study, the MB3 and AZ80 Mg alloys were welded by tungsten inert gas welding process with different filler wires. The influences of Al content in filler metal on weld morphologies, microstructure and mechanical performances were studied. Experimental results reveal that the seam width of joint increased with the improvement of welding current and pores occurred in the weld seam with excessive heat input. In the weld seam zone, a great deal of Mg 17 Al 12 precipitated phases occurred owing to the Al element in filler wire, which resulted in the enhanced metallurgical bonding and the increased micro hardness. The maximum tensile strength of 208 MPa was obtained with optimal current of 80 A and AZ61 filler wire, representing an 85% joining efficiency relative to MB3 Mg alloy parent plate. And fracture occurred at weld seam zone, revealing the potential point of joint strength improvement.
