The article of researches is the stress-strain state, flowages, mechanical properties, structure and composition of connections. A purpose of work is creation of thermodeformative and thermodynamic bases of the diffusive welding and soldering with pressure in the vacuum of homogeneous and heterogeneous materials. Mechanical properties of materials, equalizations and parameters of creep of steel and heatproof nickeliferous alloys, are certain, verification the utillized methods of design of the stress-strain state is conducted. Conformities to the law of influence of deformations of creep and structural transformations are set on the stress-strain state of connections, and also management this state at the diffusive welding. The computer design of the fields of own tensions and deformations is conducted in knots from heterogeneous materials taking into account a creep. Set influence of retrofitting of the connected surfaces on a wis, and also possibility of activating of a vacuum environment application of fluorine ammonium and F-B- ammonium. Thermodeformative and thermodynamic bases of connection of materials, recommendation and technology of the diffusive welding and soldering of concrete knots, not yieldings to the world level are developed. The method of the diffusion welding is developed with the deformed state and modification of surfaces guided tensely. Methods are protected Patents on an invention and on an useful model.
