Experimental and Numerical Investigation of the Hot Forging Process of Titanium Alloy Gas Turbine Compressor Blade
Author(s):
Abstract:
Hot forging of the aerofoil blades has complicated mechanical and metallurgical characteristics therefore; it needs numerical and experimental investigations. In this research, hot forging process of a titanium alloy aerofoil blade has been analyzed by finite element method. Then experimental tests have executed. For the numerical simulation, first material behavior of the titanium alloy has been investigated then friction factor has been obtained by ring test. Using the process simulation, material flow, die cavity filling, strain and temperature distribution, forging load and lateral forces applied the dies during the forging process have been investigated. In the next stage, trial tests have been executed. At last, numerical results have been compared with the experimental results. Results show that the forging process has been done successfully and simulation results have a good agreement with the experimental results.
