Titanium aluminide, TiAl, is an intermetallic chemical compound. It is lightweight and resistant to oxidation and heat, however it suffers from low ductility. The density of γ-TiAl is about 4.0 g/cm³. It finds use in several applications including automobiles and aircraft. The development of TiAl based alloys began circa 1970. The alloys have been used in these applications only since about 2000.
A method for joining titanium aluminide to niobium using a titanium interlayer and the joint
The application provides a method for connecting titanium aluminum carbide and niobium by adopting a titanium intermediate layer and a connected joint, and relates to the technical field of welding. The method comprises the following steps: S1, preparing a component to be connected; the component to be connected is formed by sequentially stacking titanium aluminum carbide base material, an intermediate layer and niobium base material from top to bottom, and the material of the intermediate layer is titanium; S2, performing discharge plasma sintering on the component to be connected under a preset air pressure to obtain a connected joint. By adopting the method, the cracking of the joint can be inhibited, the decarburization or Al evaporation of Ti3AlC2 at high temperature can be inhibited, thereby the deterioration of the base material is inhibited; the generation of brittle intermetallic compounds can be avoided, which is helpful to improve the interface bonding strength, thereby the strength of the connected joint is improved.
