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.

期刊介绍： The journal Crystal Research and Technology is a pure online Journal (since 2012). Crystal Research and Technology is an international journal examining all aspects of research within experimental, industrial, and theoretical crystallography. The journal covers the relevant aspects of -crystal growth techniques and phenomena (including bulk growth, thin films) -modern crystalline materials (e.g. smart materials, nanocrystals, quasicrystals, liquid crystals) -industrial crystallisation -application of crystals in materials science, electronics, data storage, and optics -experimental, simulation and theoretical studies of the structural properties of crystals -crystallographic computing
