TC11 titanium alloy is an α+β heat-resistant titanium alloy, which is mainly used to manufacture parts such as aircraft compressor discs and blades. It is the main titanium alloy material for domestic aviation engines. It has been widely used in the rotating parts of rocket engines. With the wide application of alloys, the requirements for its various technical indicators are becoming more and more stringent.
In the deformed semi-finished products of titanium alloys, especially in the deformed semi-finished products of two-phase titanium alloys, the alloy composition, the original structure of the blank, the heating system, the deformation rate, the uniformity of the deformation and the deformation temperature conditions are the most important. The basic factors affecting the final macrostructure of the bar. Factors and different organizations can greatly change the mechanical properties of semi-finished products. Researchers used forging and rolling equipment to produce TC11 titanium alloy bars with specifications of Φ73mm and Φ29mm, respectively, to study the influence of different heat treatment processes on their structure and performance.
