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.

期刊介绍： Russian Metallurgy (Metally) publishes results of original experimental and theoretical research in the form of reviews and regular articles devoted to topical problems of metallurgy, physical metallurgy, and treatment of ferrous, nonferrous, rare, and other metals and alloys, intermetallic compounds, and metallic composite materials. The journal focuses on physicochemical properties of metallurgical materials (ores, slags, matters, and melts of metals and alloys); physicochemical processes (thermodynamics and kinetics of pyrometallurgical, hydrometallurgical, electrochemical, and other processes); theoretical metallurgy; metal forming; thermoplastic and thermochemical treatment; computation and experimental determination of phase diagrams and thermokinetic diagrams; mechanisms and kinetics of phase transitions in metallic materials; relations between the chemical composition, phase and structural states of materials and their physicochemical and service properties; interaction between metallic materials and external media; and effects of radiation on these materials.
