Hypothesis

The bonding temperature significantly affects the microstructure and mechanical properties of AZ31/Zn/Sn/5083 diffusion joints.

Conclusion

The study found that varying the bonding temperature alters the joint's microstructure and mechanical properties, with the highest shear strength achieved at 339 °C.

Supporting Evidence

  • The maximum hardness value of the joints was 538 HV at the Mg-Zn IMC layer of the joint at 336 °C.
  • The highest shear strength of 78.3 MPa was achieved for the joint at 339 °C.
  • The shear fracture mode of all joints was brittle fracture.

Takeaway

This study looked at how changing the temperature affects how well two different metals stick together, finding that higher temperatures make them stick better.

Methodology

The study used solid-state diffusion bonding and TLP diffusion bonding with a Zn/Sn composite interlayer, examining the microstructure and mechanical properties at different bonding temperatures.

Limitations

The bonding temperature range was narrow, and slight changes in temperature significantly affected the joint structure.
