 Abstract
Titanium and its alloys can be usually joined with brazing method. And the alloys should be brazed at low temperature to keep their original microstructure. In this study, the mechanical strength and microstructure of the CP-Ti joint-brazed with filler metal having melting temperature of were investigated. The tensile strengths of the joint-brazed at with of cooling rate showed more than 400 MPa which was as high as base metal. The structure consisting of Ti and phase was observed in the joint area. However, the tensile strengths of the joint-brazed at with of cooling rate were decreased and the Ti, and phases were observed at the joint area. It is believed that the laves phases could decrease the mechanical strength of the joint and the cooling rate should be controled to get high strength of the titanium joint.
