Background technique
TiAl alloy is that have relatively low density, high specific stiffness, specific strength and excellent antioxygenic property and good
The material of the advantages that mechanical behavior under high temperature got well, it is considered to be ideal, the novel light high temperature knot with wide application prospect
Structure material.γ-TiAl-base alloy density is lower than the half of Ni based high-temperature alloy, and its specific stiffness and specific strength are above
Ni based high-temperature alloy.Therefore, TiAl-base alloy is the candidate material ideal instead of Ni based high-temperature alloy.But from processable
Property and economy for, single use TiAl-base alloy processing integrated member use is unpractical.By TiAl alloy and Ni
Both based high-temperature alloy connects together, and the two is used in combination, can not only have the advantages that, but also can largely save precious titanium money
Source can be very good two kinds of materials of performance and economize on resources and improve the mutual supplement with each other's advantages in performance, in many necks such as aerospace
There is extremely wide prospect of the application in domain.
Since TiAl alloy has apparent black brittleness and hot cracking tendency, it is difficult to obtain using traditional fusing soldering method
Satisfied jointing.Therefore, people using diffusion connection and method for welding realize TiAl alloy itself and with other materials
Connection.Report at present about soldering connection TiAl alloy is more, but connects about the soldering of TiAl alloy and Ni based high-temperature alloy
Connect hardly seen report.Since TiAl alloy and Ni based high-temperature alloy are applied in hot environment mostly, therefore, it is necessary to select
Solder system resistant to high temperature.
Domestic Chen Bo etc. with Ti-13Zr-21Cu-9Ni (mass fraction) solder vacuum brazing Ti3Al based alloy with
GH536 nickel base superalloy, joint bending stiffness only has 86MPa, and (Chen Bo, bear Warburg Pincus, Mao Wei wait true using Ti-Zr-Cu-Ni
