Abstract
The use of bimetallic materials in aviation and space technology is driven by high operational requirements imposed on components and the overall product. A key requirement is the reduction of the total weight and cost of the product, which is achieved by using bimetallic compositions to join parts operating in aggressive environments, elevated or cryogenic temperatures, and high pressures. Bimetals allow combining the advantages of different materials while providing the necessary specific properties for a particular location. The search for new possible applications of bimetals to reduce the mass characteristics of the product without sacrificing strength, tightness, vacuum tightness, and other operational requirements is an ongoing process to improve both the design of the aerospace system and the technology of its production.
