Abstract
Regularities were established in the effect exerted by plastic strains on formation of the stress-strain state in diffusion bonding of pieces of dissimilar materials in the form of cylinders and sleeves under compression and variable temperature conditions. It is shown that the lowest level of plastic strains and their unfavourable distributions along the axis of cylinders and sleeves take place in bonding of materials under compression and constant temperature conditions.
Keywords: diffusion bonding, dissimilar materials, stressstrain state, plastic strains, compression, temperature As shown by our earlier investigations of the fields of
