Abstract

The structure and properties of titanium/aluminum–magnesium alloy explosive welds and the influence of the magnesium content on the weld strength are studied. The welded joints of VT1-0 titanium with AMg5 and AMg6 alloys are found to fail during both welding and the application of an external load along the near-boundary zone of an aluminum alloy, and the fracture is brittle. This fracture is shown to be due to the formation of a thin aluminum alloy interlayer with a refined structure consisting of equiaxial grains less than 1 μm in size at the joint boundary, and the boundary of this structure with the base metal is a stress concentrator.
