Effect of Zn alloy interlayer on interface microstructure and strength of diffusion-bonded Mg–Al joints

The diffusion-bonding of Mg–Al without and with Zn alloy interlayer has been investigated. The addition of Zn alloy interlayer improves the microstructure of Mg–Al joints. The intermetallic phases exist in the form of dispersive particles and a thin layer of about 1 μm thickness. The shear strength...

Zusammenfassung:The diffusion-bonding of Mg–Al without and with Zn alloy interlayer has been investigated. The addition of Zn alloy interlayer improves the microstructure of Mg–Al joints. The intermetallic phases exist in the form of dispersive particles and a thin layer of about 1 μm thickness. The shear strength of joints is doubled by using the Zn alloy interlayer.
