Since diffusion bonded joint is formed from atomic migration across an interface without a liquid phase, the interface is homogeneous microstructure and hence mechanical properties are not different from those of the matrix metal. However, it is not easy to control process variables at high temperature. This paper presents diffusion bonding process and a machinery with tool material selection to develop diffusion bonding press machine for joining complex contoured metals using hot forming and diffusion bonding technology.
