In the application of various titanium alloy products, forgings are mostly used in gas turbine compressor discs and medical artificial bones that require high strength, toughness and high reliability. Therefore, not only high dimensional accuracy is required for forgings, but also materials with excellent characteristics and high stability are required. For this reason, it is necessary to give full play to the characteristics of titanium alloy in the manufacturing process of titanium forgings to obtain high-quality forgings. Titanium alloys are difficult to forge and are prone to cracks. Therefore, the most important thing in the production of titanium alloy forgings is to properly control the forging temperature and plastic deformation.
Application fields of titanium alloy forgings:
1. The field of aerospace
50% of the world's titanium materials are used in the aerospace field. 30% of the body of military aircraft uses titanium alloys, and the amount of titanium used in civil aircraft is gradually increasing. In the aerospace field, titanium alloy forgings are used in the fuel tanks of rocket and satellite propulsion engines, the shell of attitude control engines, the blades of liquid fuel turbopumps and the inlet section of suction pumps.
2. Turbine blades for power generation
Increasing the length of the blades of the steam turbine for thermal power generation is an effective measure to improve the power generation efficiency, but lengthening the blades will increase the load on the rotor.
