Abstract: The present invention relates to a method for brazing heterogeneous molybdenum and titanium alloys. The present invention includes (a) a first heating step in which an Ag-Cu-based filler metal is arranged at a bonding portion of the molybdenum and titanium alloys, heating is performed up to 25°C to 100°C under the melting point of the Ag-Cu-based filler metal, and the state is maintained for a predetermined period of time; (b) a secondary heating step in which heating is performed up to 25°C to 100°C over the melting point of the Ag-Cu-based filler metal in the first heating step and the state is maintained for a predetermined period of time; and (c) a cooling step in which the Ag-Cu-based filler metal is cooled. According to the present invention, the melting point is much lower than the phase transformation temperature of Ti and Ti wettability is excellent, and thus no phase transformation is caused in the Ti alloy and sound brazing bonding is possible.

Abstract: The present invention relates to a brazing method for bonding dissimilar materials such as a titanium alloy and a stainless steel comprising: a step (a) for heating a Ni-based filler metal at 25-100°C which is over a melting point of the Ni-based filler metal after arranging the Ni-based filler metal on a binding part of a titanium alloy and a stainless steel; a first maintaining step (b) for maintaining the Ni-based filler metal for a fixed hour at 25-100°C which is over a melting point of the Ni-based filler metal; and a step (c) for cooling the Ni-based filler metal, and comprising a second maintaining step for maintaining a fixed temperature in heating of the (a) step. Especially, a melting point can be lowered by alloying between Ni and a titanium alloy since a Ni-based filler metal is used. Therefore, since diffusion between a titanium alloy and a stainless steel is promoted, sound brazing bonding can be performed. [Reference numerals] (AA) Start; (BB) End; (S10) Assembling stage; (S11) Titanium alloy; (S12) Stainless steel; (S13) Filler metal; (S15) Arrange a binding part between a stainless steel and a titanium alloy of the filler metal; (S20) Heating stage; (S21) Start heating of the filler metal; (S22) Maintain the temperature of the filler metal during heating; (S23) Finish heating of the filler metal; (S30) Holding stage; (S31) Maintain the temperature of the filler metal after heating is finished; (S40) Cooling stage; (S41) Cool the filler metal
