Abstract:
The main difficulty in obtaining adapters from stainless steel + zirconium metal
combination lies in the formation of fragile intermetallic compounds at the weld border. By its
properties, zirconium is very close to titanium, and therefore the manufacture of tubes from this
combination, as well as pure titanium, is considerably difficult. Optimum explosion welding
parameters have been developed, ensuring the highest adhesion strength compared to the existing
production methods. At the weld border, a structure characteristic of compounds of dissimilar
metals was revealed. The permissible heating temperatures for this combination are determined.
The fundamental possibility of using the explosion energy as a factor stimulating the connection of
dissimilar metals in order to obtain high-quality multilayer tubes, billets and products for various
purposes is demonstrated, resulting in the introduction of environmentally friendly technology.
Economic analysis of the manufacturing technology of bimetallic tubes by welding explosion was
carried out. The cost-effectiveness of manufacturing technology of bimetallic stainless steel +
zirconium metal compound nozzles, which is based on the use of high-pressure gradients and
loading velocities to create production, was evaluated.
