Transient liquid phase bonding of steel using an Fe-B interlayer
Transient liquid phase bonding processes have been performed to join two carbon steel tubes using Fe96.2B3.8wt% amorphous ribbons as interlayers. Welding experiments were performed at the temperature T≈1,250°C for different durations and under pressures of 2, 3 and 4MPa. From metallographic inspecti...

| Sumario: | Transient liquid phase bonding processes have been performed to join two carbon steel tubes using Fe96.2B3.8wt% amorphous ribbons as interlayers. Welding experiments were performed at the temperature T≈1,250°C for different durations and under pressures of 2, 3 and 4MPa. From metallographic inspection it is concluded that the bonding process ends in 7.0min if a pressure of 4MPa is applied whereas the process results incomplete if less pressure is applied. A 1D model using a finite element method has been developed for the simulation of a transient liquid phase bonding process. This model was applied to the bonding of steel/Fe-B glassy metals/steel. The computed results allow us to understand the role played by the variables involved in the bonding process. © Springer Science+Business Media, LLC 2007. |
