Popis:	AZ31B magnesium alloy and 2024 aluminum alloy were successfully jointed at aid of mechanical stirring with Sn–Zn–Al filler metal. The microstructure, fracture morphologies, and mechanical properties of joint were investigated. The results show that Mg–Al intermetallic compounds can be avoided by the process. But, a small quantity of porosity is found in the joint. The shearing strength of joint interface adjacent to magnesium alloy is 35.4 MPa for formation of Mg–Sn intermetallic compounds, which is about 46 % of that of filler metal. While, the shearing strength of joint interfaces adjacent to aluminum alloy is 70.4 MPa for formation of Zn–Sn–Al solid solution, which is about 92 % of that of filler metal.
