Abstract Scope |
The friction assisted solid state joining process of dissimialr metal pipes is proposed. The joining process is designed to have two stages. In the first stage, a copper pipe rotating with a mandrel breaks the oxide lalyers at the interface of copper and aluminum pipes. In the second state, the madrel rotate alone against the stationary copper pipe to induce diffusion bonding between the copper and aluminum pipes. The result of microstructural anlysis and mechanical testing shows that solid state joining between the copper and aluminum pipes for a light-weithg heat exchanging component is successfully achieved. |
