This paper presents the prediction results of the temperature change during the
solidification process of the cylinder head made of the AC2A aluminum alloy. Prediction results
have been obtained by using the FDM solidification analysis based on two different solidification
models were investigated. Here, the solidification model means functional relationship between the
Temperature and the Fraction Solid. The first model is a simple Linear function and the second
model is estimated from DSC measurement. The comparison between the simulated and measured
temperatures of the aluminum cylinder head revealed that the selection of solidification models
significantly reflects the prediction results. The DSC model gives higher prediction accuracy of the
temperature change than the Linear model. The solidification models estimated by using Thermo-
Calc and UMSA [3] were also investigated.
