Abstract: The methods of diffusion welding and pack rolling in two cycles experimental samples were made of composite materials, differing in functional properties: the superconducting multilayer tape based alloy Nb-50Ti, stabilized with copper and refractory material with a layered structure. From the X-ray spectral analysis concluded that interdiffusion between the layers in multilayer composites with the formation of expected alloys and chemical compounds occurred mainly due to the diffusion of niobium and carbon. Due to the high mobility of atomic carbon was able to penetrate all the structural components of the composite and to form the reinforcing phase in the form of carbide precipitates and layers of silicon-carbon chemical compound.
