Effect of interlayer composition on the microstructure and strength of diffusion bonded Mg/Al joint

Formation of zinc interlayer texture during dissimilar ultrasonic spot welding of magnesium and high strength low alloy steel

“…From the results of the point analysis and examination of the Mg-Zn phase diagram [20], the IMCs could be the phase of Mg 7 Zn 3 . This phase was also reported in the literature [9], However other phases of Mg-Zn were also reported during the welding when Zn was used as an interlayer [4,21]. In the present study, no oxidation was found at Mg/ Fe interface, whereas Liu and Zhao reported oxidation in Mg/steel joint using laser-gas tungsten arc hybrid welding technique [10], which deteriorates mechanical strength of the joint.…”

Microstructure characterization and tensile properties of Mg/Al dissimilar joints manufactured by thermo-compensated resistance spot welding with Zn interlayer

“…This is attributed mainly to the following: (1) [18][19][20] where Mg-Al IMCs could be restricted, and the joint strength be improved significantly.…”

Binding property of Al/Mg/Al thin plates fabricated by one-pass hot rolling with different reduction ratios, temperatures and annealing treatments

“…6a, b, which could improve the bonding strength [22]. However, with the rolling temperature increasing, lots of intermediate phases generated both in Al side and in Mg side, in other words, the cracking of the laminated plates start with intermediate compound layer as shown in Fig.…”
