文摘
- •
High Nb-containing TiAl alloy and Ti60 alloy was brazed using Ti-28Ni filler.
- •
Increasing brazing temperature promoted the diffusion of Ni atoms into substrates.
- •
Ti2Ni phase and Ti3Al phase were harmful to the joining properties.
- •
The maximum shear strength of the joints was ∼140 MPa.
