Abstract
To establish a simple design method for a desirable interface shape based on theoretical analysis, the relation between the order of stress singularity (λ power) and actual bonding strength is evaluated with various combinations of bonded dissimilar materials. With the analysis method of secant stiffness modulus, the calculation model at the different bonding temperatures can be replaced by applying calculation model of secant stiffness modulus in varied combinations.Thus, in this paper the correlation between λ power and experimental bonding strength was investigated under several bonding temperature conditions. The investigation was carried out with a cylindrical TiB2-Ni joint by varying the interface edge angle. Actual bonding strength was evaluated from the tensile test, and λ power was calculated by substituting secant stiffness moduli into Bogy's equation for each interface angle condition.From these results, the dependency of material combinations on the relationship between λ power and actual bonding strength was clarified. Desirable interfaces with arbitrary material combinations were also discussed for achieving high strength joint. It was clarified that residual stress could be reduced and actual bonding strength increased by employing a desirable interface shape. The most desirable interface edge angle was shown for several combinations of bonded dissimilar materials.
