【Abstract】 By using 2 D finite element method (FEM) and experiment, the phenomenon of heat conduction in TC11 Ti alloy compressor blade is simulated and analyzed during the post forge cooling course, and the time_variation characters and distribution laws of transient temperature fields of every airfoil section are obtained. The results presented in the paper provide a reasonable basis for studying post_forge irregular twisting.更多还原
