| Abstract Scope |
In this study, the effect of Ce content on the solidification structure of AH36 steel ingot is investigated through a Cellular Automata-Finite Element (CAFE) solidification microstructure prediction model, validated by laboratory vacuum induction melting and casting experiments. Numerical simulation reveals that increasing Ce content increases the equiaxed grain ratio significantly, gets higher grain density and a notable reduction in average grain size. Experimental results confirm the numerical predictions, demonstrating that the addition of 53 ppm Ce increases the equiaxed crystal ratio from 6.45% to 12.73% while reduces the average grain size from 1526.68 μm to 927.21 μm. Further increasing the Ce content to 89 ppm enhances the equiaxed crystal ratio to 17.57% and decreases the average grain size to 529.79 μm, resulting in a pronounced refinement of the prior austenite grains. |
