Abstract. Solid phase bonding is an effective method for joining dissimilar metals. Solid phase bonding is the bonding method without fusing metal matrix. Using this method, clad metal which is joined with sheet metals is in practice. However, the parameters to achieve stable cold-forge solid phase bonding in bulk are not well known. To investigate the parameters that affect the solid phase bonding state, a new test method to evaluate the strength of the bonding interface obtained by cold forging was developed. Using this method, test pieces bonded with S10C/A1070 and SUS304/A1070 were made in fluctuating interface bonding parameters (the surface area expansion ratio, the surface pressure). Although tensile test results showed large variation in joining strength at low value of bonding parameters, bonding was strong enough to exceed the A1070 base metal strength at the region of high value of bonding parameters. As it was found that the bonding parameters were able to measure the effect on joining strength in this experiment, it is considered that bonding parameters for solid phase bonding can be evaluated by the newly developed test method.
