摘要：

In　order　to　joining　wrought　magnesium　alloy　AZ31B　sheet　using　soldering　manner.　High-frequency　induction　soldering　of　wrought　magnesium　alloy　AZ31B　using　Zn　was　investigated.　Both　the　interface　microstructure　and　the　mechanical　properties　of　the　soldered　joint　were　studied.　The　interface　microstructure　and　formation　phases　of　the　soldering　seam　were　investigated　by　scanning　electron　microscopy,　X-ray　diffraction　and　X-ray　energy　dispersive　spectrometer.　The　tensile　strength　of　the　soldered　joint　and　the　microhardness　of　the　interface　microstructure　were　tested.　The　results　show　that　Zn　react　with　the　base　metal,　and　α-Mg　matrix　and　α-Mg+γ-MgZn　eutectoid　structure　are　formed　in　soldering　seam.　The　average　tensile　strength　of　the　butted　joint　is　52　MPa　and　the　average　shearing　strength　of　the　overlapped　joint　is　38　MPa.　The　fracture　morphology　of　the　soldered　joint　exhibits　intergranular　fracture　mode　and　the　fracture　comes　from　α-Mg+γ-MgZn　eutectoid　structure.
