The paper presents investigation of the properties of joint region in the two-layer Mg/Al material semi-finished product obtained by the explosive welding method. Aluminum 1050A and magnesium alloy AZ31 were used to fabricate the bimetallic material to be analyzed. The Mg/Al materials were made using different technological parameters of explosive welding. In this work an analysis of microstructure changes on the cross-sections of the joint region was conducted. There were also made tests of layers connections quality. The results of the research show a deviation in microstructure in the bonding area. Analysis of the results shows that for all used parameters of the explosive welding method guarantee a permanent connection of the both magnesium and aluminum layers.Keywords: Explosive welding, two-layer Mg/Al materials, microstructure, bond strength
