✦ Synopsis

By using the real information of the intended bonding surface and considering the effect of the diffusion distance in a definite time, a new theoretical model for diffusion bonding was proposed. The effects of different operating mechanisms, bonding parameters and microstructures on bonding were investigated. The simulation results indicate that, it is vital to consider the real information of the intended bonding surfaces and the effect of diffusion distance in a definite time; the metastable microstructure and the stable ultrafine microstructure exhibit better bonding characteristic than that of the original stable microstructure, which is in agreement with experimental results.
