TC11 alloy is a type of material with good comprehensive properties α-β Type A thermal strength titanium alloy has excellent thermal strength properties (high temperature strength, creep resistance, etc.) below 500 ℃, and has high room temperature strength. The alloy also has good Hot working processability (including conventional processability and superplasticity), and can be welded and machined in various ways. Currently, with the continuous expansion of the application of TC11 alloy, the β Heat treatment and isothermal forging have achieved rapid development.

This alloy is mainly used for manufacturing compressor discs, blades, drums and other parts of aircraft engines, and can also be used for manufacturing aircraft structural components. adopt α+β Zone thermal deformation and α+β The maximum long-term working temperature of TC11 alloy obtained through zone heat treatment is 500 ℃. The semi-finished products produced include bars, forgings, die forgings, and castings.
