| Abstract: | The solidification temperature field and microstructure of superalloy castings were simulated by synthetically using the universal modeling software PRO/E,the finite element analysis software ANSYS and the applied software MATLAB,which has powerful functions of calculation and graphics.In this paper,the efficient CA-FE method coupling micro-kinetics with macro-thermal transfer was developed.Moreover,this method was used to simulate the solidification temperature field and the microstructure of an aeroengine superalloy casting produced by investment casting.The simulated results agree well with the actual experiments. |
| Keywords: | CA-FE method computer simulation aeroengine superalloy casting |
