| Abstract: | The interfacial structure of the Mg/Al diffusion-bonded joint was studied by means of SEM, EPMA and TEM. The test results indicated that the interface zone of Mg/Al diffusion-bonded joint included the transition region on Mg side, the mid-diffusion region and the transition region on Al side. The concentration distribution of Mg and Al atoms in the diffusion zone includes three different regions. The three regions are intermetallic compounds Mg2Al3, Mg3Al2 and MgAl, respectively. The location of Mg2Al3, Mg3Al2 and MgAl phases in the diffusion zone can be determined. The Mg3Al2 phases were observed in the transition region on Mg side by means of TEM. |
