Microstructure Evolution of the K4169 Superalloy Blade Based on Cellular Automaton Simulation

A two-dimensional cellular automaton model has been developed to simulate the process of microstructure evolution of K4169 superalloy blade produced by investment casting. The dynamic process of grain-structure formation of the blade castings without chemical refiner or with refiner during solidific...

Summary:A two-dimensional cellular automaton model has been developed to simulate the process of microstructure evolution of K4169 superalloy blade produced by investment casting. The dynamic process of grain-structure formation of the blade castings without chemical refiner or with refiner during solidification can be observed real-time on the computer. A CA model coupling micro-kinetics with macro-thermal transfer is adopted to calculate the feature of grain microstructure. The results show that the simulated grain structure is in good agreement with optical micrographs.
