The investigation of the interface connection area of the three-layer tube "steel / vanadium alloy / steel" after different deformation-heat treatments was performed. Furthermore, a qualitative and quantitative analysis of the structure of the three-layer material were conducted, including analysis of the contact area of the steel and the vanadium alloy and the diffusion layer between them was obtained. The analysis of the microstructure and mechanical properties (microhardness, ultimate tensile strength, yield strength and elongation) of three-layered material has been carried out.
