Brazing titanium base amorphous brazing method, preparation method thereof and alloys of tc4

The present invention relates to a titanium-based amorphous brazing , and their preparation method of brazing alloys of TC4. It is intended to solve the conventional high-melting point solder, poor weldability technical problems. The solder of the present invention consists of TiaZrbNicCudMe and unavoidable impurities, a is 35 ~ 37, b is 35 ~ 37, c is 8 ~ 12, d is 13 ~ 16, e is 2 ~ 5, a + b + c + d + e = 100, M is Sn , Al, V is at least one. Low melting point brazing material of the present invention, welding performance is good, substantially free of precipitated phases compound, its TC4 alloy brazing weld has good tensile strength, since Al, V, and added / or Sn, the solder process been refined microstructure, the solder wettability and flowability is significantly enhanced.
