We have studied the stress-strain state (SSS) at loading by compression and temperature variation, in order to optimize the process of diffusion welding and brazing of assembles from dissimilar materials with soft interlayers. Materials having different thermal coefficient of linear expansion (TCLE) and the same moduli of elasticity were joined. An example of such joints can be those of magnetic and nonmagnetic steels produced with application of diffusion welding with soft interlayers or pressure brazing using filler metals based on copper with silicon, manganese and boron additives. Sufficient strength of materials in the brazed assembly is combined with plastic deformation of just the interlayer. Fields of all the components of stresses and strains, as well as their diagrams in different assembly sections were studied. Analysis of simulation results showed that tangential and equivalent stresses in the butt zone (on the interface), determining formation of physical contact and activation of the process of joint formation in diffusion welding, at simultaneous loading of assemblies with a soft interlayer rise considerably in material with higher TCLE at cooling and in material with lower TCLE at heating. Distribution of plastic deformations in the interlayer is more uniform, i.e. thermal cycling under pressure promotes formation of physical contact and activation of processes of joint formation in such assembles. 8 Ref., 10 Figures.
