Turbine blades are one of the core components in turbines, used to convert the energy of fluids (such as steam, gas or water) into mechanical energy. These blades are designed very precisely to maximize energy conversion efficiency while withstanding harsh conditions such as high temperature, high pressure and high speed rotation. Turbine blades play a vital role in aircraft engines, power plants and various propulsion systems.

Forging usually uses high-quality metal materials, such as nickel-based alloys, titanium alloys, etc. These materials have excellent high-temperature strength and corrosion resistance and can meet the requirements of turbine blades under extreme working conditions.
Through the forging process, a uniform grain structure and excellent mechanical properties, such as high tensile strength, high hardness and good toughness, can be achieved in the turbine blades, thereby improving the fatigue resistance and service life of the blades.
Forging enables precise control of blade geometry, including the blade's shape, cross-sectional profile and internal structure, ensuring the blade has good aerodynamic performance and dynamic balance.
The forging process can effectively reduce or eliminate internal defects in turbine blades, such as pores, inclusions, etc., improve the material density and uniformity of the blades, and reduce the risk of material fatigue cracks.
Compared with other manufacturing processes, forging can usually achieve effective utilization of materials, reduce waste, and improve production efficiency and cost-effectiveness.
The forging process is suitable for a variety of metal materials and complex blade structures, and can meet the manufacturing needs of different types of turbine blades, including aerospace engines, gas turbines, automotive turbochargers, etc.
