(Industrial Application Field) The present invention relates to a Ti-containing composite brazing material used for Ti, Ti alloys, ceramics, etc., and a method for manufacturing the same. (Prior art and its problems) Conventionally, Ti-containing noble metal solders have been alloyed with Ti.
Plastic working is difficult due to the formation of intermetallic compounds between the alloy and various metals, so in order to manufacture titanium-containing solder, alloy powder is obtained by atomizing molten metal, or a precious metal alloy is used as an intermediate layer and Ti is added to the surface of the alloy.
Or, conversely, plates or tapes were used in which titanium was used as an intermediate layer and the surface was clad with a noble metal alloy. However, the Ti-containing powder brazing filler metal obtained by the atomization method has limited uses due to its shape, and has not been able to satisfy the needs of many users. On the other hand, although composite brazing filler metals made of Ti and precious metal alloys are effective in terms of plastic workability, it takes time for Ti and precious metal alloys to melt and form an alloy during brazing. In the past, there was a problem of segregation. (Objective of the Invention) The present invention has been made to solve the above problems, and is easy to plastically work, completes alloying in a short time during brazing, and even after alloying.
The present invention aims to provide a Ti-containing composite brazing filler metal whose structure is uniform and which does not adversely affect bonding strength such as segregation, and a method for producing the same. (Structure of the Invention) The Ti-containing composite brazing filler metal of the present invention is one in which Ti is uniformly dispersed in an Ag-Cu alloy in the form of a single metal, and the manufacturing method is such that Ti grains and Ag-
Cu alloy grains are mixed in proportions according to their composition ratios, compression molded and sintered multiple times, and then plastically processed by drawing or rolling to obtain a wire or plate-shaped material. It is something. In particular, by using this method, which involves repeating compression molding and sintering multiple times, Ti is uniformly dispersed in the Ag-Cu alloy braze in the form of a single metal, resulting in Ti intermetallic compounds. do not have. Even if it were to occur, it would only be a surface layer of Ti, so the material after plastic working, that is, extrusion, could be easily finished to a predetermined size by drawing or rolling without losing plastic workability. In addition, by repeating compression molding and sintering multiple times, a Ti-containing composite brazing material dispersed in finer fibers can be obtained.
When this Ti-containing composite brazing filler metal is used to braze Ti, Ti alloys, or ceramics, the Ti is uniformly mixed with Ag.
- Since it is dispersed in the Cu alloy, molten alloying can be completed in a short time, the structure after brazing has extremely little segregation, and the joint strength is improved compared to conventional ones. Next, specific examples and conventional examples will be described in order to clarify the effects of the Ti-containing composite brazing filler metal and the manufacturing method thereof according to the present invention. (Example) Ti with an average particle size of 1 mm and Ag-Cu28% were mixed at a ratio of 5:95, and this was filled into a 50φmm mold.
After compression molding to 30 tons, it was heated to 1 at 730℃ in an Ar atmosphere.
After sintering for a time, increasing compression molding to 70 and 100 tons, and repeating compression and sintering, 150 tons of hot compression molded material was extruded to obtain a wire material of 12φmm. By repeating drawing and annealing, this
mm, the width is changed to 4.3 mm by rolling process.
A tape with a thickness of 0.3 mm was obtained. (Conventional example) Thickness on both sides of Ti tape with thickness of 1.05mm and width of 7mm
Ag-Cu28% tapes of 4.5 mm and width 7 mm were joined by welding to form a sandwich-shaped tape, which was annealed and rolled repeatedly to a thickness of 0.3 mm.
As a final finish, a tape with a width of 4.3 mm was obtained using a slitter. These tapes were used as a brazing material to braze Ti rods of 2 mm x 1.5 mm square as lap joints, and the cross-sectional structure was observed under a microscope for segregation and a joint strength comparison test was conducted, as shown in the table below. I got similar results.

(Effect of the invention) As explained above, the brazing filler metal of the present invention has Ag-Cu
Since Ti is uniformly dispersed in the alloy in the form of a single metal, it is easy to form an alloy during brazing, and there is little segregation after brazing, resulting in a high bonding strength. Furthermore, since the method of the present invention does not produce intermetallic compounds, plastic working is easy and brazing filler metal of any shape can be easily produced.
