Abstract

The development of energy, rocket and space, and cryogenic technologies requires the development of technologies for producing titanium-steel composites with guaranteed performance properties under high pressures, loads, and low and elevated temperatures. Traditional welding methods (melting or rolling) heat the metal interface to temperatures that lead to the formation of intermetallic compounds and titanium carbides, resulting in a sharp decrease in the strength and ductility of layered composite materials. Under optimal conditions, the fast explosive welding process prevents diffusion processes from developing, and the resulting titanium-steel composites are free of brittle inclusions. However, with subsequent operational heating above 600 °C, the formation of intermetallic layers at the interface between metals is possible, therefore, for such titanium-steel structures, it is advisable to use composites with intermediate layers between titanium and steel, eliminating or reducing the intensity of diffusion processes.
