Welding addition Nb controls Ti for filling metal2The generation of the weld metal zone brittle intermetallic things such as Ni, crack sensitivity is reduced, reaches elimination
The purpose of weld crack.
Therefore the characteristics of the advantages of considering electron-bombardment welding and Nb, it is high using vacuum electron beam welding method, addition
Fusing point Nb is filling metal, the method for electronic beam current deviation titanium alloy side, makes the poor titanium alloy of thermal conductivity with Nb in electronics
Melted under Shu Zuoyong, Nb high-termal conductivity transfers heat to TiNi alloy side and forms weldering in the fusing point less than TiNi alloy
Joint, unfused Nb play physical barrier effect, hinder titanium alloy to be combined with TiNi, prevent weld to split so as to realize
Line prevents the generation of intermetallic compound while generation, agitaion of the scanning beam to molten bath makes molten pool metal uniform
Distribution, segregation is reduced, increases substantially strength of welded joint.
