Abstract
The self-fusion solidification bonding process occurs the isothermal fusion and the isothermal solidification by the reaction diffusion between the base metal and the dissimilar insert metal. The bonding process is carried out below the melting points of the base metal. 60/40 brass was used as the insert metal for the self fusion solidification bonding of aluminum in this study. The periodic motion under the load control was applied to the bonding interface at the bonding temperature. The joint by 60/40 brass insert metal was obtained at the bonding temperature of 893 K. The phases by the isothermal fusion and solidification in the bond were evaluated by the chemical composition of the phase and the ternary phase equilibrium diagram.
