Abstract
It has been established that creep processes at a transient stage used in diffusion bonding of heat-resistant alloys reduce the time of formation of a physical contact between the mating surfaces. Bonding of billets of a heat-resistant alloy in the austenised and aged states, or utilisation of spacers in a structural state differing from that of the base metal, allows intensification of the processes of interaction of the mating surfaces and provides properties of the joints at a level of those of the base metal.
Keywords: heat-resistant alloys, diffusion bonding, creep, structural state, dislocation structure, mechanical properties
