摘要：

Available databases presently used by commercial simulation software packages for the aluminum casting industry usually come with material properties for only a few selected standard alloys. In the case of other alloys with different chemical compositions and refinement or modification treatment, thermal analysis could be an invaluable tool in order to gain necessary properties. The aim of this paper is to characterize the solidification paths of Al-Si5-Cu(1-4) alloys and quantify the amount of solid fraction using cooling curve analysis. The correlation between solid fraction and temperature has been determined using Newtonian and Fourier techniques of base line. Both techniques are also briefly described in this paper. The obtained results have been compared with results obtained using available commercial software (e.g., Pandat and JMatPro).
