TC11
TC11 variety introduction
The nominal composition of TC11 titanium alloy is Ti-6.5Al-3.5Mo-1.5Zr-0.3Si, which is a heat-resistant titanium alloy of α-β type, with an aluminum equivalent of 3.5 and a molybdenum equivalent of 7.3.
The alloy also has good thermal workability (including conventional process properties and superplasticity), and can be welded and machined in various ways.
The β heat treatment and isothermal forging of the alloy have been developed rapidly.
The alloy is also sensitive to thermal salt stress corrosion.
TC11 application
The alloy is mainly used in the manufacture of compressor discs, blades, drums and other parts of aircraft engines, and can also be used in the manufacture of aircraft structural parts.
Through thermal deformation and heat treatment in the α-β zone, the maximum long-term operating temperature of the alloy is 500℃. The semi-finished products are bars, forgings and die forgings.TC11 Titanium alloy is a high temperature Titanium alloy widely used in Chinese aviation, with a maximum operating temperature of 500℃. It is mainly used in parts of aero engine compressors, such as blades, discs, drums and shafts. Can also be made into shaped castings.
The working conditions of the parts are that they can be used for 500 hours below 500℃ and 100 hours below 550℃ and 1000 hours below 450℃ in the annealed state, and can be used for parts working for 100 hours below 50℃ and parts working for one time below 700℃ in the strengthened treatment state.
