Prediction of the grain size of inoculated aluminium alloy castings is of great interest for both academic research and industrial application. In this paper, by reviewing the grain size prediction models, the important influence of solute diffusion layer in front of the grain growth front on the final grain size has been addressed. An analytical approach to calculate the thickness of the solute diffusion layer in the melt is proposed, based on which the scale of diffusion layer thickness is evaluated.
