Research Progress in Low Temperature Brazing Technology for Advanced Aeronautical Titanium Alloys

The research progress in titanium alloys brazing at the temperatures below 800 ℃ is introduced from brazing filler metals and technology. The effects of microelements on the melting point and wettability of low temperature filler metals, such as Ag-based, Al-based and Ti-Zr based filler metals, as well as the influence of low temperature brazing process parameters on the properties of welded joints of titanium alloy are summarized. The future development direction of brazing technology for advanced aeronautical titanium alloy is pointed out.
