Microstructure Evolution Simulation of Laser Cladding Process Based on CA‐FD Model
In this paper, a cellular automata‐finite difference (CA‐FD) model is established to simulate the microstructure evolution in the laser cladding process. The microtemperature field, crystal nucleation, and growth in the solidification process of Inconel 625 alloy cladding layer are researched, and the effects of different cladding process parameters on crystal growth are studied. The CA‐FD model is improved based on the temperature and sequence of phase formation in the solidification process of the cladding layer, so as to realize the simulation study of the phase transformation process in the Inconel 625 alloy cladding layer. Finally, the laser cladding experiment of Inconel 625 alloy is carried out, and the simulation results are verified.
