High-Temperature Alloy Forging for Engine Turbine Blades

Turbine blades are core components of aero-engines and gas turbines, enduring extreme conditions of high temperature, high pressure, and high-speed rotation for extended periods. To ensure their performance and reliability, high-temperature alloy forging technology has become a crucial process for manufacturing turbine blades.

High-temperature alloys (such as nickel-based and cobalt-based alloys) possess excellent high-temperature strength, oxidation resistance, and creep resistance. Through precision forging processes, alloy grain size can be refined, mechanical properties enhanced, and internal defects reduced. During the forging process, precise control of temperature, deformation rate, and cooling rate is required to ensure structural uniformity and dimensional accuracy. Furthermore, advanced technologies such as isothermal forging and hot die forging further improve the fatigue life and high-temperature resistance of the blades.

Forged turbine blades not only outperform cast blades but also reduce material waste and lower costs. As aero-engines evolve towards higher thrust-to-weight ratios, high-temperature alloy forging technology will continue to be optimized, providing critical support for the manufacture of next-generation turbine blades.
