Abstract
Stress-strain state (SSS), allowing for plastic creep strains, in cylindrical parts of metals with different physical-mechanical properties in diffusion bonding was studied by computer modelling based on the finite element method. The mechanisms of creep in diffusion bonds, as well as formation of SSS in them, were established.
