英文摘要	Pure Cu is brazed with amorphous Cu68.5Ni15.7Sn9.3P6.5 (wt.%) filler metal in a vacuum furnace. The effects of dwelling time and brazing temperature on the tensile strength and microstructure of the brazed joints are investigated. The bonding mechanism of the joints is also discussed. It is found that the tensile strength firstly increased and then decreased with increasing dwelling time or brazing temperature. The brazed joints contain -Cu13.7Sn86.7, -phase Cu3P and (CuNi)2P phase. The content of brittle Cu3P governs the tensile strength of the joints. The maximum tensile strength of the brazing joints is found to be 135 MPa when brazing was performed at 680°C for 20 min. In addition, the bonding mechanism of the joints shows the characteristics of contact reaction brazing before the temperature reaches the melting point. The fractured surface is characterized by brittle fracture. © 2016, UK Simulation Society. All Rights Reserved.
