Abstract

In this paper, a novel Al-Mg-Zn filler metal was designed to join magnesium alloy AZ31B plates by means of high-frequency induction brazing in argon gas shield condition. The microstructure and the mechanical properties of the brazed joint were investigated. The experimental results showed that the brazed joint contained large amount of α-Mg and β-Mg₁₇(Al, Zn)₁₂ phases. The homogeneous Mg₃₂(Al, Zn)₄₉ phase in the original filler metal was consumed due to the intensive alloying during the brazing process. The results indicate that the shear strength of the brazed joint is 35 MPa. The fracture morphology of the brazed joint exhibits intergranular fracture mode, and the fracture originates from the hard β-Mg₁₇(Al, Zn)₁₂ phase.
